Given the numerical expression:

4^-3 / 4^-8

Determine what the expression is equivalent to.

Solution:
In dividing numbers with different exponents, we apply the rules of exponents.

Let a and b represent any number

n represent the exponent

a^n / b^n = (a/b)^n-n

We will now apply the rule to the given numerical expression.

=4^-3 / 4^-8

= 1 ^ -3 - (-8)

= 1^-3 + 8

= 1x10^5 or 100,000

4/^-3 / 4^-8 = 100,000
