Question
Rationalise the denominator of the following expression. That is, find an equivalent expression that does not have a square root in the denominator. Give your answer in it's simplest form.13+3‾√=
Solution
The expression you provided seems to be incomplete or incorrectly formatted. However, I'll provide a general method to rationalize the denominator of an expression.
If you have an expression of the form a + √b, where a and b are some numbers, you can rationalize the denominator by multiplying the numerator and denominator by the conjugate of the denominator. The conjugate of a + √b is a - √b.
Here are the steps:
-
Multiply the numerator and denominator by the conjugate of the denominator. In this case, if the denominator is a + √b, the conjugate is a - √b.
-
Distribute in the numerator and use the difference of squares formula (a^2 - b^2 = (a - b)(a + b)) in the denominator.
-
Simplify the expression if possible.
Please provide the complete expression so I can give a more specific answer.
