Answer 1

Answer:

(c) correct answer

Step-by-step explanation:

a= (✓3+✓2)^2/ (✓3-✓2)^2 1/a= (✓3-✓2)/ (✓3+✓2) n b also same

(✓3-✓2)^2/ (✓3+✓2)^2+ (✓3+✓2)^2/ (✓3-✓2)^2

here(a+b)^2 and (a -b)^2 formula use

then, 5-2✓3✓2/5+2✓3✓2+5+2✓3✓2/5-2✓3✓2

do LCM and use again use (a+b)^2 n (a-b)^2 formula

then u will get

25+24-20✓3✓2+25+24+20✓3✓2/ 25-10✓3✓2+10✓3✓2-24

98/1=98. once true this on paper then u will understand...
