Question

A.√2+√32= ?
b.√6+√54-√250= ?
c.√32-√2+√8= ?
d.4√3-(√27+√12) = ?

Answer 1

A.√2+√32= √2 + √16.2 = √2 + 4√2 = 5√2
b.√6+√54-√250= √6 + √9.6 - √25.10 = √6 + 3√6 - 5√10 = 4√6 - 5√10
c.√32-√2+√8= √16.2 - √2 + √4.2 = 4√2 - √2 + 2√2 = 5√2
d.4√3-(√27+√12) = 4√3 - (√9.3 + √4.3) = 4√3 - (3√3 + 2√3) = 4√3 - 5√3 = -√3
