I don't understand how this works, help

Answer 1

Answer:

[See Below]

Step-by-step explanation:

✦ So when we see $x^{2}$, these are powers or exponents.

  ✧ We solve them like this:

• $7^{2}= 7*7$

• $7*7=49$

✦ So the answers would be:

• $5^{2}=25$

• $(-16)^{-2} =-0.00390625$

• $\frac{1}{8^{2} }=0.015625$
