Question

calcule o valor de; A) 144^-1/2 B) 27^2/3 C) 16^3/4 D) 16^5/2 E)0,09^-1/2 F) 8^-1/2

Answer 1

Explicação passo-a-passo:

a) 144 -½= ( 1/144)½= √1/144= 1/12

b) (27)⅔= (3³)⅔= 3²=9

c) (16)¾= (2⁴)¾= 2³=8

d) (16)^5/2= (2⁴)^5/2= 2^20/2= 2^10= 1024

e) (0,09)-½= (9/100)-½= (100/9)½= √ 100/9= 10/3

f) (8)-½= (1/8)½= √ 1/8= 1/√8= √8/√64= √8/8
