Question

me ajudem :)

A|  $10^{2}$ X $10^{4}$ X $10^{3}$ =

B| $10^{2}$ X $10^{3}$ X $10^{-5}$ =

C| $10^{2}$ : $10^{-2}$ =

D| ($10^{2}$)³ X $10^{-5}$ =

Answer 1

observe que é mesma base (10) ...

a) $10^2.10^4.10^3 = 10^2^+^4^+^3 = 10^9$

b) $10^2.10^3.10^-^5 = 10^2^+^3^-^5 = 10^0 = 1$

c) $\frac{10^2}{10^-^2} = 10^2^-^(^-^2^) = 10^4$

d) $10^2^.^3 . 10^-^5 = 10^6^-^5 = 10^1 = 10$
