Question

rationalize the denominator of 5/root 10 +root 5​

Answer 1

Step-by-step explanation:

to rationalize we just multiply and divide the term in denominator with opposite signs

so,

5/√10 + √5

5 * (√10 - √5)/ (√10)² - (√5)²

as (a+b)(a-b) is a² - b²

5(√10-√5)/5

= √10 - √5/1

since there is no root term in denominator we can say that the above expression is rationalized
