Answer:

[See Below]

Step-by-step explanation:

✦ So when we see [tex]x^{2}[/tex], these are powers or exponents.

  ✧ We solve them like this:

  • [tex]7^{2}= 7*7[/tex]
  • [tex]7*7=49[/tex]

✦ So the answers would be:

  • [tex]5^{2}=25[/tex]
  • [tex](-16)^{-2} =-0.00390625[/tex]
  • [tex]\frac{1}{8^{2} }=0.015625[/tex]
