Answer 1

Answer: Here's your answer after a long time : )

1) (-3/4)^3 ÷ (-3/4)^5

= (-3/4)^(3-5)

= (-3/4)^(-2)

= (-4/3)^2    

(Important point - To make the power positive, we reciprocate the base)

= -16/9

2) (1/5^2)^2 x (1/5)

= (1/25)^2 x (1/5)

= (1/50) x (1/5)

= 1/250

4) (2/3)^2 ÷ [(2/3)^2]^0

= 4/9 ÷ 1 ---   ( 2/3)^2= 4/9^0 = 1 because a^0 = 1 )

= 4/9 ÷ 1 = 4/9

5) [(1/2)^5 ÷  (1/2)^3] - [(1/2)^6 ÷ (1/2)^5]

= [1/2^5-3] - [(1/2^6-5)]

= (1/2)^2 - (1/2)^1

= 1/4 - 1/2

= -(1/4)
