To simplify the expression \( \frac{12^2}{4^2} \), we can start by calculating each part separately.

  1. Calculate \( 12^2 \): \[ 12^2 = 144 \]

  2. Calculate \( 4^2 \): \[ 4^2 = 16 \]

Now, substitute these values into the expression: \[ \frac{12^2}{4^2} = \frac{144}{16} \]

Next, simplify \( \frac{144}{16} \): \[ \frac{144}{16} = 9 \]

We recognize that \( 9 = 3^2 \).

Thus, the expression \( \frac{12^2}{4^2} \) simplifies to \( 3^2 \).

The only option among the choices given that is equal to \( 12^2 / 4^2 \) is \( 3^2 \).

So, the correct answer is: \[ 3 \text{ to the power of 2} \]

which expression is equal to (5 to the power of 8) to the power of 4?

1 over 5 to the power of 32
1 over 5 to the power of -4
5 to the power of -4
1 over 5 to the power of -32

To simplify the expression \( (5^8)^4 \), we can use the power of a power rule of exponents, which states that \( (a^m)^n = a^{m \cdot n} \).

Applying this rule:

\[ (5^8)^4 = 5^{8 \cdot 4} = 5^{32} \]

Now, we will compare this result with the options given:

  1. \( \frac{1}{5^{32}} \)
  2. \( \frac{1}{5^{-4}} \)
  3. \( 5^{-4} \)
  4. \( \frac{1}{5^{-32}} \)

Among these options, none of them directly represent \( 5^{32} \).

However, we can rewrite some expressions using the properties of negative exponents:

  • \( \frac{1}{5^{-32}} = 5^{32} \)

This means the expression \( \frac{1}{5^{-32}} \) is equal to \( 5^{32} \).

So the answer is: \[ \frac{1}{5^{-32}} \]

wrong it wasn't -32 it was 32

Apologies for the confusion in my previous response. Let's clarify the situation.

We simplified the expression \((5^8)^4\) correctly:

\[ (5^8)^4 = 5^{8 \cdot 4} = 5^{32} \]

Now, we look at the given options again:

  1. \( \frac{1}{5^{32}} \)
  2. \( \frac{1}{5^{-4}} \)
  3. \( 5^{-4} \)
  4. \( \frac{1}{5^{-32}} \)

From these options, only \( \frac{1}{5^{32}} \) is clearly not equal to \( 5^{32} \).

None of these options equal \( 5^{32} \), which we have found is the correct form of the expression.

Therefore, the expression \( (5^8)^4 \) simplifies to \( 5^{32} \), and none of the options provided are equal to this result.
