Question 553467
4- squareroot3/2-squareroot3

Rationalize the denominator by multiplying above term by (2+squareroot3), we get

> {(4- squareroot3)*(2+squareroot3)}/{(2-squareroot3)*(2+squareroot3)}

> {(8-(2squareroot3)+(4squareroot3)-3}/(2-3)

Rearranging similar terms, we get

> (5+2squareroot3)/-1

> -(5+2*1.73)

> -8.46         Ans
