Answer:

In the world of exponents, 4 is the number being raised by the exponent, which is 2.

Let's answer the first question:

If the base is 4, what is the value if the exponent is 2?

  • The base is 4 and the exponent is 2.  We would multiply 4 two times.

4^2= 4*4 = 16

So, it would be 16.

Let's answer the second question:

What if the exponent is -2?

<u>This is the rule for negative exponents:</u>

a^{-x}=\frac{1}{a^x}

Using this rule, we can solve 4^{-2}.

4^{-2}= \frac{1}{4^2}=\frac{1}{16}

So, our answer for the 2nd question is 1/16.
