Question

What is the smallest number by which 219700 must be multiplied to get a perfect cube?​

Answer 1

Answer:

10

Step-by-step explanation:

First do factorisation u willl get

2, 2, 5, 5, 13, 13, 13(factors)

ie 2*2*5*5*13*13*13

=2^2*5^2*13^3

we require to multiply 2 to make it 2 cube and 5 to get 5 cube

hence we multiply 2 and 5 to the number

2*5=10

I think u understand hope it is not complicated

Shortcut there are 2 xeroes a cube has three zerooes hece 10 would be definetly multiplied this a hint we get actualy
