Question

In each expression below the numbers under the root sign all add to the same number, 10. Determine which expression is greatest. How?

a) √7+ √3
b) √6+ √4
c) √8+ √2

Answer 1

Explanation:

I think a calculator is the only way to solve this question:

`√(7) +√(3) = 2.96\\\\√(6) +√(4) = 2.54\\\\√(8) +√(2) =3.07`

So (c) is the greatest.
