Q. Simplify. Express your answer using positive exponents.

\newline

(4a^8)(6a^4)(7a)

Multiply coefficients: Multiply the coefficients $4$ , $6$ , and $7$ . $\newline$ Calculation: $4 \times 6 \times 7 = 168$
Add exponents: Add the exponents of $a$ . $\newline$ Calculation: $a^8 \times a^4 \times a = a^{(8+4+1)} = a^{13}$
Combine results: Combine the results from previous steps. $\newline$ Calculation: $168 \times a^{13}$
