Question

URGENTE!!! Se a=(0,00001) elevado a menos 2 e b = (10 elevado a2)elevado a 3,calcule;
a)a•b
B)a/b
C)b/a

Answer 1

a = (0,0001)^(-2)
a = 10^(-4)^(-2)
a = 10^8

b = (10^2)^3= 10^6

A)
a.b
= 10^8.10^6
= 10^(8+6)
= 10^(14)

B)
a/b
= 10^8 /10^6
= 10^(8-6)
= 10^2

C)
b/a
= 10^6/10^8
= 10^(6-8)
= 10^(-2)
