Exercise 19 Page 3

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

- 15z^9

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.

- 5z^4(3z^5)

CommutativePropMult

Commutative Property of Multiplication

(- 5 * 3)(z^4 * z^5)

Multiply

- 15(z^4 * z^5)

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

- 15z^9
