Question

one third the sum of square of a and cube of b ​

Answer 1

Answer:

Which number when squared is one-third of its cube?

It's simple, the number will be 3 .

N.B : It can be zero too. But most of the time it is mentioned or we assume that the number is not equal to zero.

Trick: Questions about the number which, when squared is (1/n)-th of its cube will have the solution of “n”.

Solution :

Let, the number be x.

So,

x2=(1/3)x3

3x2=x3

Or,

(x2)(x−3)=0

If x is not equal to zero then,

x−3=0

Or,

x=3

So, the number will be 3 (or zero, as nothing is mentioned about x, in the question and we assumed x is not equal to zero)
