Question

pls help me with this pls anyone who knows it tell me fast​

Answer 1

Step-by-Step Explaination:

9. = {[(3√7)/(√5+√2)]×[(√5-√2)/(√5-√2)]} -

{[(5√5)/(√2+√7)]×[(√2-√7)/(√2-√7)]} +

{[(2√2)/(√7+√5)]×[(√7-√5)/(√7-√5)]}

= {[3√7(√5-√2)]/[(√5)²-(√2)²]} -

{[5√5(√2-√7)]/[(√2)²-(√7)²]} +

{[2√2(√7-√5)]/[(√7)²-(√5)²]}

= {[(3√35+3√14)]/(5-2)} - {[5√10-5√35]/(2-7)} +

{[2√14-2√10]/(7-5)}

= [(6√49)/3] - [-√15/5] + [√4/2]

I hope it is helpful to you
