Q. Simplify. Express your answer using positive exponents.

\newline

(8r^4)(9r)(2r)

Multiply Coefficients: Multiply the coefficients $8$ , $9$ , and $2$ . $\newline$ Calculation: $8 \times 9 \times 2 = 144$
Multiply Variables: Multiply the variables using the exponent rule (add the exponents). $\newline$ Calculation: $r^4 \times r^1 \times r^1 = r^{(4+1+1)} = r^6$
Combine Results: Combine the results from the previous steps. $\newline$ Calculation: $144r^6$
