Q2:


5√(72)-3√(32)


5√(36) √(2) -3√(16) √(2)


5*6√(2)-3*4√(2)


30√(2)-12√(2)

Q5:


(√(3x^2y^3))/(4√(5xy^3))


(√(3)xy√(y))/(4√(5)y√(x)√(y))

Cancel off
√(x):


(√(3)y√(x)√(y))/(4√(5)y√(y))

Cancel off
y:


(√(3)√(x)√(y))/(4√(5)√(y))

Cancel off
√(y) :


(√(3)√(x))/(4√(5))

Multiply
√(5) on the numerator and denominator:


(√(3)√(x)√(5))/(4√(5)√(5))


(√(15)√(x))/(20)
