Question

if m+n=4, find least value of m^2+n^2​

Answer 1

Answer:

The least value of m^2 + n^2 is 8

Step-by-step explanation:

The value of m^2 + n^2 will be the least when,

m=n

Therefore,

m+n = 4

2m = 4

m = 2

This gives us m = n = 2

Thus, our answer is 2^2 + 2^2 = 8

Answer 2

Answer:

8

Step-by-step explanation:

For m²+n² to be minimum, the difference b/w m & n must be 0

i. e m=n=2

So,m²+n²=2m²=8
