SIMPLIFY 1.(3+√2)/√2 2. 4/(1+√3) 3.(3+√5)(1-2√5) 4.(3+√8)/((2√3)-4)

Square root.

(3+√2)/√2 = (3√2 + 2)/2 4/(1+√3) * (√3-1)/(√3-1) = 4(√3-1)/(3-1) = 2(√3-1) (3+√5)(1-2√5) = 3 -5√5 - 10 = -7-5√5 (3+√8)/((2√3)-4) * (2√3 + 4)/(2√3 + 4) = (3+√8)(2√3 + 4)/(12-16) = (6√3 + 2√24 - 12 - 4√8)/-4 = (12 + 8√2 - 6√3 - 4√6)/4
