Question

1. (2a²b)(4ab²)

Explanation:

Step1: Multiply the coefficients

$2 \times 4 = 8$

Step2: Combine like terms for $a$

$a^2 \times a = a^{2+1} = a^3$

Step3: Combine like terms for $b$

$b \times b^2 = b^{1+2} = b^3$

Step4: Multiply all results

$8 \times a^3 \times b^3$

Answer:

$8a^3b^3$
