How do I simplify √18-√54+2√50?

Help. I don’t even need the steps if someone can just post the answer

? Best Answer

not sure what you mean by simplify, but if you consider this simplification, then that’s how you do it.

√18 = √(9*2) = √9*√2 = 3√2

√54 = √(9*6) = √9*√6 = 3√6

2√50 = 2*√(2*25) = 2*√25*√2 = 2*5*√2 = 10√2

therefore, you have, any of the below answers are “simplified”…

3√2 – 3√6 + 10√2 = 3√2 – 3√3√2 + 10√2 = (13-3√3)√2 = 13√2 – 3√6.
