Question

evaluate the expression.
$(3.2 \times 10^4) \times (1.5 \times 10^3)$
$4.8 \times 10^{?}$

Explanation:

Step1: Group coefficients and powers

$(3.2 \times 1.5) \times (10^4 \times 10^3)$

Step2: Multiply the coefficients

$3.2 \times 1.5 = 4.8$

Step3: Multiply the powers of 10

$10^4 \times 10^3 = 10^{4+3} = 10^7$

Step4: Combine the results

$4.8 \times 10^7$

Answer:

$7$
