Evaluate two raised to the power of
three.
Two raised to the power of three is
written two with a superscript three after it. We know that raising any number to
the power three means cubing it and that cubing any number involves multiplying the
number by itself then itself again. Two cubed is equal to two
multiplied by two multiplied by two. As multiplication is commutative
and associative, we can multiply these numbers in any order. But for this example, we will work
from left to right. Two multiplied by two is equal to
four, so we’re left with four multiplied by two. As four multiplied by two is equal
to eight, we know that two cubed or two raised to the power of three is equal to
eight.
