Question

Evaluate each of the following and express with an appropriate prefix: (a) (430 kg)^2 (b) (0.002 mg)^2, and (c) (230 m)^3

Answer 1

a)0.185g^2

b)4μg^2( Micrograms)

c)12.167hm^3( cubic hectometer)

Step-by-step explanation:

To solve this problem, we must first use the calculator to solve each of the points, then knowing the number of zeros on the left or on the right, we choose a unit with which it is better to see the unit

A)

(430 kg)^2=184900kg^2=0.185g^2

B)

(0.002 mg)^2=4x10^-6mg^2=4μg( Micrograms)

c)

(230 m)^3=12167000m^3=12.167hm^3( hectometer)
