Question

a) 10³.10²
B) 10₈: 10₅
C)2₄.5₄
D) 2-².3-².5-²
E)60³:12³
F)250₄ : 125₄
G)(2²)³
h) (10-₁)⁻²

Answer 1

A) 10³.10² =  10^5


B) 10₈: 10₅ = 10^13

C)2₄.5₄ = (2.5)^4 ==> 10^4 

D) 2-².3-².5-² = (2.3.5) ^-2 = 30^-2 ==> (1/30)^2

E)60³:12³ = ( 60:12)^3 ==> 5^3

F)250₄ : 125₄ = (250/125)^4 ==> 2^4 

G)(2²)³ = 2^6

h) (10-₁)⁻² = 10^2
