Answer 1

To determine which of the provided responses results in the answer of 1, let's evaluate each option:

1. 3(80): This equals \(3 \times 80 = 240\).

2. 13 − (7.42)0: The expression \((7.42)^0 = 1\) (any non-zero number raised to the power of 0 is 1), so this evaluates to \(13 - 1 = 12\).

3. (−2.97)0: Here \((-2.97)^0 = 1\) (again, any non-zero number raised to 0 is 1).

4. 50 + 90: This equals \(50 + 90 = 140\).

Now, let's summarize the results:

• 3(80) = 240
• 13 − (7.42)^0 = 12
• (−2.97)^0 = 1
• 50 + 90 = 140

The only expression that results in 1 is (−2.97)0.

Answer 3

Let's evaluate the expressions in each of the provided options step by step to determine which shows the correct process for solving \( -3^0 + 4.5 \).

1. Option 1:
   \(-30 + 4.5 = -3 + 4.5 = 1.5\)

   • This is incorrect because \(-30 + 4.5\) does not equal \(-3\).

2. Option 2:
   \(-30 + 4.5 = (-3)^0 + 4.5 = 1 + 4.5 = 5.5\)

   • Evaluating \((-3)^0\) gives 1, so this part is correct, but \(-30 + 4.5\) does not equal \((-3)^0\).

3. Option 3:
   \(-30 + 4.5 = -1 \cdot 30 + 4.5 = -1 \cdot 1 + 4.5 = -1 + 4.5 = 3.5\)

   • This option is incorrect. The calculations do not follow the original problem.

4. Option 4:
   \(-30 + 4.5 = -3 \cdot 0 + 4.5 = 0 + 4.5 = 4.5 \)

   • This option is incorrect as \(-3 \cdot 0\) equals 0 but doesn’t represent \(-3^0\).

We need to clarify that the expression \(-3^0\) (if interpreted without parentheses) generally evaluates as \(-(3^0)\):

• \( 3^0 = 1\) thus, \(-3^0 = -1\).

Based on this reasoning, the evaluation is: \[ -3^0 + 4.5 = -1 + 4.5 = 3.5. \]

None of the provided options present the correct solving process using the original expression, \( -3^0 + 4.5 \). But option 3 correctly results in \(3.5\), aligning with our computation despite the misleading notation. Thus, the best option from the given responses is option 3.

Answer 5

To evaluate the expression \(7(-5.3)^0 + 4 \cdot 9\) using the Zero Power Rule, we need to apply the rule that any non-zero number raised to the power of 0 equals 1.

Here's how we compute it step by step:

1. Applying the Zero Power Rule:
   \((-5.3)^0 = 1\), because any non-zero number raised to the power of 0 equals 1.

2. Substituting back into the expression:
   \[7(-5.3)^0 + 4 \cdot 9 = 7(1) + 4 \cdot 9 = 7 + 36\]

Now, let's look at the available response options:

1. 71 + 4⋅9:
   \[ 7(1) + 4 \cdot 9\]
   This expression simplifies to \(7 + 36\), which is correct.

2. 70 + 4⋅9:
   This implies \(7(0) + 36\), which is incorrect because it doesn't apply the Zero Power Rule accurately.

3. 75.3 + 4⋅9:
   This doesn't make logical sense in the context of the Zero Power Rule since it involves a misinterpretation of the terms.

4. 75.30 + 36:
   This is also incorrect as it does not simplify correctly based on the Zero Power Rule.

From the evaluations, the correct equivalent expression is:
71 + 4 ⋅ 9 (which simplifies correctly to \(7 + 36\)).

Answer 7

To find an equivalent expression to the given expression \(12(9 - 7^0) + (-29)^0\), we'll first simplify it step by step.

1. Evaluate \(7^0\):
   According to the Zero Power Rule, any non-zero number raised to the power of 0 is equal to 1. Thus, \(7^0 = 1\).

2. Evaluate \((-29)^0\):
   Similarly, \((-29)^0 = 1\) because any non-zero number raised to the power of 0 is also 1.

3. Substituting back into the expression:
   We can substitute \(7^0\) and \((-29)^0\) into the original expression:
   \[ 12(9 - 1) + 1 \] This simplifies to: \[ 12(8) + 1 = 96 + 1 = 97. \]

Now let's examine the response options:

1. Option 1: \(12(9 - 0) + 0\)
   This simplifies to \(12(9) + 0 = 108\). Not equivalent.

2. Option 2: \(12(2) + 1\)
   This simplifies to \(24 + 1 = 25\). Not equivalent.

3. Option 3: \(12(9 - 1) - 1\)
   This simplifies to \(12(8) - 1 = 96 - 1 = 95\). Not equivalent.

4. Option 4: \(12(9 - 1) + 1\)
   This simplifies to \(12(8) + 1 = 96 + 1 = 97\). This is equivalent.

Based on the calculations, the correct equivalent expression is Option 4: \(12(9 - 1) + 1\).

Answer 9

To solve the expression \(-4(3 + 12^0) + 15^0\) using the Zero Power Rule, we first need to simplify it by applying the Zero Power Rule, which states that any non-zero number raised to the power of 0 equals 1.

Steps:

1. Calculate \(12^0\): \[ 12^0 = 1 \]

2. Calculate \(15^0\): \[ 15^0 = 1 \]

3. Substituting back into the expression: \[ -4(3 + 1) + 1 \]

4. Now simplify: \[ -4(4) + 1 = -16 + 1 = -15 \]

Now, let's evaluate the response options to find which one correctly corresponds to these calculations:

1. Option 1: \[ -4(3 + 12^0) + 15^0 = -4(15) + 1 = -60 + 1 = -59 \]

   • This option is incorrect because \(3 + 12^0 = 4\) not \(15\).

2. Option 2: \[ -4(3 + 12^0) + 15^0 = -4(15) + 15 = -60 + 15 = -45 \]

   • This option is incorrect for the same reason as the first.

3. Option 3: \[ -4(3 + 12^0) + 15^0 = -4(3 + 1) + 1 = -4 \cdot 4 + 1 = -16 + 1 = -15 \]

   • This option matches what we computed.

4. (Incomplete Response): This doesn't show a complete expression or answer.

Conclusion

The correct response that shows the right process is Option 3: \[ -4(3+12^0) + 15^0 = -4 \cdot 4 + 1 = -16 + 1 = -15 \]

Option 3 correctly includes the calculation process and leads to the correct equivalent expression.
