(4/5)^3 = (4/5) x (4/5) x (4/5) = (16/25) X (4/5) = 64/125
64/125 = 0.512
If you want to make sure that you're right:
Ask yourself: If 4/5 is cubed, will it equal 64/125?
Now use this equations to represent that equation:
(4/5)^3 = 64/125
take the cubed root of both sides to get...
4/5 = 4/5
Both sides are equal, hence the solution is true.

One of the rules on exponents says:
(4/5)^3 = (4^3) / (5^3)
Therefore:
(4/5)^3 = 64/125

4/5=0.8
You only need to multiple the decimals since the number is < 1.
=> 8^3 = 8*8*8 = 512.
There are three decimal places.
=> 0.512.
