Okok im really bad at exponents, help :(
i wrote the options on there btww

Subtract the lower exponent from the higher one. (4 from 8)

8 - 4 = 4

The base stays the same, so a = 3, and the exponent is now 4, so b = 4.

Now find 3^4 by multiplying.

3 × 3 × 3 × 3 = 81

a = 3

b = 4

c = 81

center= (-2,0)

radius= sqrt2/2
