Answer 1

Answer:

46656

Step-by-step explanation:

Let the number= x

then as per question;

x/4= a² => x=4a²

x/27=b³ => x=27b³

4a²=27b³

a=3n, b=2m

4*(3n)²=27*(2m)³

4*9n²=27*8m³

n²=6m³ => minimum of m=6, n= 6²=36

=======

a=3n= 108

b=2m= 12

x=4a²= 4*108²= 46656

x=27b³= 27*12³= 46656

Answer: minimum number to satisfy the given condition is 46656
