Answer 2

Step-by-step explanation:

sorry cuz now I can only solve a and b . the following are the steps to solve the above questions.

• to rationalize the denominator, we have to multiply it with its R.F to get a rational number.
• but the value of the surd must not change. that's why we multiply it by 1.
• here value does not change. we can write 1 as (√5 -√2)/(√5 -√2). so now we will simplify it.
• and we will get the answer.
• this is very simple to do.
