The subsets of the real numbers are the irrational numbers, rational numbers, integers, whole numbers, and the natural numbers. First, figure out where does -18 belong? Well, -18 is a rational number because it can be expressed as a fraction of two integers. It's also an integer.
So, it doesn't belong in the sets of irrational numbers, whole numbers, and the natural numbers.

A 23 is at 100%
When evaluating b^2c^-1 for b=8 and c=4, the answer is -16
E = b^2c–1
x-a = 1/xa
E = b^2c - 1
= 8^2 x (-4)-1
= 64/-4
= -16
