What is the value of c in the equation below?
a: -4
b: -2
c: 1/64 (fraction)
d: 1/4 (fraction)

When multiplying indices you add them to one another. So in this case, you would do -4 + 2 = -2

This means that it is 2^-2 or, in other words, a=2 and b=-2. This means that c is 2^-2

This is the same as 1/2^2 which is 1/4. So c = 1/4
