Answer:
a)0.185g^2
b)4μg^2( Micrograms)
c)12.167hm^3( cubic hectometer)
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)
