First find 2 products of the numbers and one has to be a perfect square.
√32 = √ 16 x 2 which is simplified to 4√ 2
√ 75 = √ 25 x 3 = 5 √3
√98 = √49 x 2 = 7√ 2
4√2 + 5√3 - 7√2
This is simplified to -3√2 + 5√3
√32 = √ 16 x 2 which is simplified to 4√ 2
√ 75 = √ 25 x 3 = 5 √3
√98 = √49 x 2 = 7√ 2
4√2 + 5√3 - 7√2
This is simplified to -3√2 + 5√3

Factor 32, 75, 98
32 = 2^5
75 = 3*5^2
98 = 2*7^2
4*sqrt(2) + 5*sqrt(3) - 7*sqrt(2) = 5*sqrt(3) - 3*sqrt(2)
32 = 2^5
75 = 3*5^2
98 = 2*7^2
4*sqrt(2) + 5*sqrt(3) - 7*sqrt(2) = 5*sqrt(3) - 3*sqrt(2)
-
√32 + √75 - √98 =
4√2 + 5√3 - 7√2 =
5√3 - 3√2
4√2 + 5√3 - 7√2 =
5√3 - 3√2
