Answer to Problem 5E
The value of expression
Explanation of Solution
The given radical expression is
Consider an expression
In order to rationalize the denominator of the given expression, the numerator and denominator of the given expression is multiplied with the value given in the denominator. That is,
Thus, the rationalized form of the expression
Use the above method and complete the rationalization of the expression
Thus, the value after rationalization is
