me ajudem por favor to com duvida

Answer 1

a) ³√5•³√6 = ³√(5•6) = ³√30

b)√2•√8 = √(2•8) = √16 = 4

c) √2•√6•√3 = √(2•6•3) = √36 = 6

d) √5•(1+√5) = √5 + √(5•5) = √5 + √25=√5 + 5 = 5 + √5

e) ³√4•³√6 =³√(4•6)=³√24=³√(8•3)=³√2³•3=³√2³•³√3
=2³√3

f)(3√2-2)(√2+3)= 3√2•√2+3•3√2-2√2-2•3
=3√(2•2)+9√2-2√2-6
=3√4 +7√2 -6
=3•2+7√2-6
=6-6+7√2
=7√2
