tolong bantu saya ...saya kesulitan mengerjakan..

a)40×(1/8)=5
b)54×(4/9)=24
c)(9/49)×147=27
d)(-64)×(-1/625)=+64/625

semoga membantu

A||

40 x ([tex] \frac{1}{2} [/tex])³
= 40 x  [tex] (2^{-1}[/tex])³
= 40 x [tex] 2^{-3} [/tex]
= 40 x 1/2³
= 40/8
= 5

B||

54 x (2/3)²
= 54 x 4/9
= 24

C||

(3/7)² x 147
= 9/49 x 147
= 27

D||

-4³ x [tex] x (-5)^{-4} [/tex]
= -64 x 1/(-5)^4
= -64/625

Semoga Membantu!!!
