Question

I don't understand how this works, help

Answer 1

[See Below]

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`

• 
  `(1)/(8^(2) )=0.015625`
