Question

Simplify the Following :-
(a) $\frac{2\sqrt{30}}{\sqrt{6}} - \frac{3\sqrt{140}}{\sqrt{28}} + \frac{\sqrt{55}}{\sqrt{99}}$

(b) $\frac{2\sqrt{13}}{3\sqrt{52} - 4\sqrt{117}}$

Answer 1

Answer:

(a)

2*√30/√6 - 3*√140/28 + √55/√99

= 2√5 - 3√5+√5/3

=(6-9+1)√5/3

= - 2√5/3

(b)

2√13/(3√52-4√117)

= 2/(3√4 - 4√9)

= 2/(3*2 - 4*3)

= 2/(6-12)

= 2/(-6)

= - 1/3
