Question

(1×61/64)-⅔ simplify​

Answer 1

$( 1\frac{61}{64}) ^{-2/3}$   = 0.64      (1 61/64)-⅔ = 0.64

Step-by-step explanation:

(1 61/64)-⅔  = $( 1\frac{61}{64}) ^{-2/3}$

$1\frac{61}{64} = \frac{64 \times 1 + 61}{64} = \frac{125}{64}$  

125/64  = 5³/4³  = (5/4)³

=> $( 1\frac{61}{64}) ^{-2/3}$   =  $((5/4)^3)^{\frac{-2}{3}}$

= (5/4)⁻²

=  (4/5)²

=  4²/5²

= 16/25

= 16 * 4 / 25 * 4

= 64/100

= 0.64

$( 1\frac{61}{64}) ^{-2/3}$   = 0.64
