Answer:

9 should me multiplied

Step-by-step explanation:

Answer 2

Step-by-step explanation:

the answer of your question is 9

it should be multiplied with 9 to get perfect cube.

you can also do it by yourself:-

first of all the no. which you have given,you have to do prime factorization of it.

at last when it is asked to get perfect cube you should make pair of 3 same digit at last you will find that 1or 2 digits are left if 2 digit are left simply you have to multiply it by same digit.

If one digit is left you have to multiply it by square of the digit left.

for example..

in this case after pairing 1 digit that is 3 is left so I have to multiply by square of left digit so I do multiplication of 3^2=9

the same procedure will be followed in finding perfect square also but in case of finding perfect square you have to make pair of 2 same digit and at last the digit which left you have to multiply by same digit.

for example ..

if 2 left so simply you have multiply by 2.

hope it helps you.....
