Question

find the smallest positive integer M,given that MN is a cube number

Answer 1

Answer:

Heya mate your answer

Step-by-step explanation:

mn = m * 2 * 10^8

mn = m * 2 * 10^6 * 10^2

mn = m * 2 * 10 * 10 * 10^6

mn = m * 2 * 2* 5 * 2 * 5 * 10^6

mn = m* 5 * 5 * 2^3 * 10^3 * 10^3

m = 5 is the smallest number to make mn a cube

then

mn = 5*5*5*2^3*10^3*10^3  

mn = 5^3*2^3*10^3*10^3

mn = 1000^3
