Question

49 is multiplied by x to get a perfect cube.The value of x is

Answer 1

Answer:

Step-by-step explanation:

Let the perfect cube be P.

As 49 = 7*7

and P = 7*7 × X

but also, P = (cube rootP)^3

so, P = 7*7×X = 7*7*7

So, X = 7

Answer 2

Answer:

Let the perfect cube be P

As 49 = 7^2

And P = 7^2 × X

but also , P = (cube root P)^3

so, P= 7×7×X =7×7×7

So, x=7
