Answer: 1
Explanation:
x^3 = 64
This means that we've to find a number that we'll multiply thrice that'll give 64. The number is 4.
Check: 4×4×4 = 64
Therefore x^3 = 64; x = 4
y^3 = 125
This means that we've to find a number that we'll multiply thrice that'll give 125. The number is 5.
Check: 5×5×5 = 64
Therefore y^3 = 125 ; x = 5
x=4, y= 5
y - x
=5 - 4
=1
