Answer:


(3.7 * 10^(-2)) (1.2 * 10^3) = 44.4

Step-by-step explanation:

Given


(3.7 * 10^(-2)) (1.2 * 10^3)

Required

Evaluate


(3.7 * 10^(-2)) (1.2 * 10^3)

Remove bracket


(3.7 * 10^(-2)) (1.2 * 10^3) = 3.7 * 10^(-2)*1.2 * 10^3

Rewrite as:


(3.7 * 10^(-2)) (1.2 * 10^3) = 3.7 *1.2* 10^(-2) * 10^3


(3.7 * 10^(-2)) (1.2 * 10^3) = 4.44* 10^(-2) * 10^3

Apply law of indices


(3.7 * 10^(-2)) (1.2 * 10^3) = 4.44* 10^(-2+3)


(3.7 * 10^(-2)) (1.2 * 10^3) = 4.44* 10^1


(3.7 * 10^(-2)) (1.2 * 10^3) = 4.44* 10


(3.7 * 10^(-2)) (1.2 * 10^3) = 44.4
