To multiply exponential numbers with the same base but different exponents, we add the exponents and keep the base the same.

H

Practice makes perfect

To multiply exponential numbers with the same base but different exponents, we add the exponents and keep the base the same. a^m* a^n= a^(m+ n) Keeping this in mind, let's simplify the given expression.

2^(- 12)* 2^3

a^m*a^n=a^(m+n)

2^(- 12+3)

Add terms

2^(- 9)

The obtained expression corresponds to option H.
