Question

please answer my question

Answer 1

$2560 = 5 \times {2}^{9}$
For a number to be a perfect cube, the powers of the prime numbers in its prime factorisation must be multiples of 3.
So, we have to make 5 to 5^3.
Thus we need to multiply it by 5^2=25.
${2}^{9} \times 5 \times {5}^{2} \\ = {2}^{9} \times {5}^{3} \\ = {( {2}^{3} \times 5) }^{3} \\ = {40}^{3}$
