Question 135220: Multiplying and Dividing Radicals
Simplify.
1) 2+√3�√3
2) √11+ 6 � √27
3) 2√7x�y� -3√18x�y
4) 48√42x� � 8 √6x
Answer by stanbon(75887) (Show Source): You can put this solution on YOUR website!
1) (2+√3)�√3 = [sqrt(3)*(2+sqrt(3)]/3 = (3+2sqrt(3))/3
---------------------------------------------------------------
2) (√11+ 6) � √27 = [sqrt(3)(sqrt(11) + 6)/9= [6sqrt(3)+sqrt(33))/9
----------------------------------------------------------------------
3) 2√7x�y� -3√18x�y = [(2sqrt(7)x^2y)/(-9sqrt(2)x^3y)][sqrt(2)/sqrt(2)]
--------------------------------------------------------------------------
= [2sqrt(14)]/[-18x] = [-sqrt(14)]/[9x]
----------------------------------------------
4) 48√42x� � 8 √6x = 6sqrt(7)x
=====================================
