Answer 1

This is the rule of exponents you need for this problem.

\(a^m \cdot a^n = a^{m + n} \)

Answer 2

ADD THE EXPONENTS.

Answer 3

Example:

\(5^{-3} \cdot 5^{13} = 5^{-3 + 13} = 5^{10} \)

Answer 4

When you have a multiplication (like the one that's showing), then you add.

When you have a division you subtract.

Multiply = Add

Divide = Subtract

Answer 5

\(\Huge\color{blue}{ \bf a^b \times a^{c}=a^{b+c} }\)

your a is 8, your b is -2, your c is 14.
