How can i write the following exponents as a fraction

(-2)³ = -8
-4⁴ = 256
= 125/216
= 1/4³ = 1/64 (every number with negative exponent is equivalent to the opposite of the number itself)

2-(-3)² = 2-(+9) = 2-9 = -7

-(-7)⁰ = -1 (every number elevated to 0 is 1)

1-3⁻¹ = 1-1/3 = 2/3

Im pretty sure it would be 6 purple rectangles.
