Question

1/2 power-3×1/4power-3×1/5power-3

​

Answer 1

Answer:

Step-by-step explanation:

Here i would use ^ symbol for power

(1/2)^-3 × (1/4)^-3 × (1/5)^-3

We know that when the exponents are the same, we just multiply the bases and write the same exponent.

Therefore

(1/2)^-3 × (1/4)^-3 × (1/5)^-3 = (1/2 × 1/4 × 1/5)^-3

= (1/40)^-3

= We know that the sign fo the exponent will be changed when the base is changed to the reciprocal of itself.

Therefore,

(1/40)^-3 = (40/1)^3

40^3 = 64000.

Hope this helps.... :)
