Answer 4

Which expression is equivalent to (6^0) -^2/6-^2

Answer 5

To simplify the expression \((4^0) - 3 \cdot 4^{-2}\), we can follow these steps:

1. Calculate \(4^0\):
\[
4^0 = 1
\]

2. Calculate \(4^{-2}\):
\[
4^{-2} = \frac{1}{4^2} = \frac{1}{16}
\]

3. Substitute these values into the expression:
\[
1 - 3 \cdot \frac{1}{16}
\]

4. Multiply \(3\) by \(\frac{1}{16}\):
\[
3 \cdot \frac{1}{16} = \frac{3}{16}
\]

5. Now, substitute this value back into the expression:
\[
1 - \frac{3}{16}
\]

6. To subtract \(\frac{3}{16}\) from \(1\), convert \(1\) to a fraction with a denominator of 16:
\[
1 = \frac{16}{16}
\]

7. Now perform the subtraction:
\[
\frac{16}{16} - \frac{3}{16} = \frac{16 - 3}{16} = \frac{13}{16}
\]

Thus, the equivalent expression is:
\[
\boxed{\frac{13}{16}}
\]

Answer 6

To simplify the expression \((2^{-1/2}) - 2^0\), we will evaluate each component step-by-step.

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

2. Calculate \(2^{-1/2}\):
\[
2^{-1/2} = \frac{1}{2^{1/2}} = \frac{1}{\sqrt{2}}
\]

3. Now substitute these values back into the expression:
\[
\left(\frac{1}{\sqrt{2}}\right) - 1
\]

4. To perform this subtraction, we can convert \(1\) to a fraction with a denominator of \(\sqrt{2}\):
\[
1 = \frac{\sqrt{2}}{\sqrt{2}}
\]

5. Substitute this back into the expression:
\[
\frac{1}{\sqrt{2}} - \frac{\sqrt{2}}{\sqrt{2}} = \frac{1 - \sqrt{2}}{\sqrt{2}}
\]

Thus, the equivalent expression is:
\[
\frac{1 - \sqrt{2}}{\sqrt{2}}
\]

If you also want to rationalize the denominator, you can multiply the numerator and denominator by \(\sqrt{2}\):
\[
\frac{(1 - \sqrt{2})\sqrt{2}}{2} = \frac{\sqrt{2} - 2}{2}
\]

Either form is valid, depending on whether or not you'd like to rationalize the denominator. Thus, we can express the final answers as:
1. \(\frac{1 - \sqrt{2}}{\sqrt{2}}\)
2. Or, when rationalized: \(\frac{\sqrt{2} - 2}{2}\)

Choose the format that suits your needs!

Answer 7

To simplify the expression \(2^{-1} / 2^0\), we'll look at each component separately:

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

2. **Calculate \(2^{-1}\):**
\[
2^{-1} = \frac{1}{2}
\]

3. **Now substitute these values into the expression:**
\[
\frac{2^{-1}}{2^0} = \frac{\frac{1}{2}}{1} = \frac{1}{2}
\]

Thus, the expression \(2^{-1} / 2^0\) simplifies to:
\[
\frac{1}{2}
\]

Therefore, the final answer is:
\[
\boxed{\frac{1}{2}}
\]

Answer 8

Thank you for the clarification.

To evaluate the expression \(2^{-1} / 2^0\), we will simplify it step by step.

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

2. **Calculate \(2^{-1}\)**:
\[
2^{-1} = \frac{1}{2}
\]

3. **Now substitute these values into the expression**:
\[
2^{-1} / 2^0 = \frac{1/2}{1} = \frac{1}{2}
\]

Thus, the expression \(2^{-1} / 2^0\) simplifies to:
\[
\frac{1}{2}
\]

If you meant \(2 - (2^{-1})\), please let me know, and I can help evaluate that expression instead. Otherwise, the final answer remains:
\[
\boxed{\frac{1}{2}}
\]

Answer 9

To simplify the expression \((6^0) - 2 \cdot 6^{-2}\), we can follow these steps:

1. **Calculate \(6^0\)**:
\[
6^0 = 1
\]

2. **Calculate \(6^{-2}\)**:
\[
6^{-2} = \frac{1}{6^2} = \frac{1}{36}
\]

3. **Substitute these values back into the expression**:
\[
1 - 2 \cdot \frac{1}{36}
\]

4. **Multiply \(2\) by \(\frac{1}{36}\)**:
\[
2 \cdot \frac{1}{36} = \frac{2}{36} = \frac{1}{18}
\]

5. **Now substitute this value into the expression**:
\[
1 - \frac{1}{18}
\]

6. **Convert \(1\) to a fraction with a denominator of \(18\)**:
\[
1 = \frac{18}{18}
\]

7. **Now perform the subtraction**:
\[
\frac{18}{18} - \frac{1}{18} = \frac{18 - 1}{18} = \frac{17}{18}
\]

Thus, the equivalent expression is:
\[
\boxed{\frac{17}{18}}
\]
