Example 3: tex2html_wrap_inline98

Since the index of the radical is odd, there is no restriction on the values

of x.

The answer is x=132.

Check the solution by substituting 132 in the original equation

for x. If the left side of the equation equals the right side of the equation

after the substitution, you have found the correct answer.

Left side: tex2html_wrap_inline118

Right side: You can also check the answer by graphing


(the left side of the original equation minus the right side of the original

equation). The solution will be the x-intercept. The x-intercept (and

hence the solution) on the graph is 5.
