Question

1) Sabendo que X=4-² e Y=2-²,Determine:

A) X×Y =

B) (X×Y)° =

C) (X×Y)¹ =

D) X:Y =

E) (X×Y)² =

F) X+Y =

G) X-Y =
​

Answer 1

Resposta:

x = 4^-2 = 1/16

y = 2^-2 = 1/4

a) 1/16*1/4 = 1/64

b) (1/64)^0 = 1

c) 1/64

d) (1/16)/(1/4) = 1/4

e) (1/64)^2 = 1/4096

f) 1/16 + 1/4 = 5/16

g) 1/16 - 1/4 = 1/16 - 4/16 = -3/16
