Question

pls solve it


its of rational and irrational number ​

Answer 1

simply rationize it

{(√2-1)(√2-1)}/{(√2+1)(√2-1)} -{(√3-√2)(√3-√2)}/(√3-2)(√3+√2)

we know

(a+b)(a-b)=a^2-b^2

using that formula in it we get

(2+1+2√2)/(2-1 )+(3+2-2√2√3)/(3-2)

now,put the given value

(3+2×1.414) +(5-2×1.414×1.732)

(3+2.828)+(5-4.898) (correcting upto three places of decimal)

5.828+.102

5.930
