Question 179812
rationalize the denominator of each expression... thanks 
key: [ means square roots 
1. [5x/[3 

= (5x)/sqrt(3)

Multiply numerator and denominator by sqrt(3) to get:

= [5xsqrt(3)]/3

= (5x/3)sqrt(3)
-----------------------------

2. 3[x2/3[4 

= 3sqrt(x^2)/3sqrt(4)

= (3x)/(3*2)

= x/2
====================
