Question
Rationalise the denominator of the following expression. That is, find an equivalent expression that does not have a square root in the denominator.To do this, multiply the expression by 2√2√.52‾√=52‾√×2‾√2‾√= Note: multiplying a number by a/a is the same as multiplying by 1!
Solution
It seems like there's a mistake in your question. The expression you want to rationalize is not clearly stated. However, I can explain the general process of rationalizing a denominator.
Here are the steps to rationalize a denominator:
-
Identify the denominator that needs to be rationalized. Let's say it's √2 for this example.
-
Multiply both the numerator and the denominator by the conjugate of the denominator. The conjugate of √2 is also √2.
-
Carry out the multiplication. For example, if your fraction is 5/√2, after multiplying by √2/√2, you get 5√2/2.
-
Simplify the fraction if possible.
Please provide the correct expression you want to rationalize so I can give a more specific answer.
