Question

If the value of the expression below is a perfect square, which could be the value of m?

expression is 10m

A: m= 2/5
B: m= 1/2
C: m=1
D: m=2​

Answer 1

A

Explanation:

`m=2/5 \implies 10(2/5)=4 \\ \\ m=1/2 \implies 10(1/2)=5 \\ \\ m=1 \implies 10(1)=10 \\ \\ m=2 \implies 10(2)=20`

Of these, only 4 is a perfect square.
