Question

128 find the smallest number by didide to obtain perfect cube

Answer 1

2 is the smallest no.
two make 128 a perfect cube divide 2 by both side
128/2=2*2*2*2*2*2*2/2
64=2*2*2*2*2*2
hence 2 is smallest no. required to make 128 a perfect cube

Answer 2

FIRST FIND THE FACTORS OF 128 = 2×2×2×2×2×2×2

NOW 2 IS NOT IN PAIR

SO, IT SHOULD BE DIVIDED BY 2 TO GET PERFACT CUBE


128÷2= 64 AND IT IS PERFACT CUBE
