Question

find the value of it​

Answer 1

Answer:

8/15

Step-by-step explanation:

1/4 - 1/64 × 8 ( 2^2 = 4, 4^3 = 64)

LCM = 64

1×16 - 1×1 / 64 × 8

16 - 1 / 64 × 8

15/64 × 8

15/8

Reciprocal of 15/8 is 8/15

Answer 2

Answer:

[(1/2)^2-(1/4)^3]×2^3

[(1/2)^2-(1/2)^6]×2^3

(1/2)^2[1-(1/2)^4]×2^3

=2[1-1/16]

=2×15/16

=15/8

Reciprocal =8/15 Ans
