Answer 1

Answer:

1)

=√2/(2+√2)* (2-√2)/(2-√2)

=(2√2-2)/2

=2(√2-1)/2

=√2-1

given √2=1.414

=√2-1

=1.414-1=0.414

2)

=[1/(3-2√2)]∧2 + [1/(3+2√2)]∧2

=[1/(3-2√2) -  1/(3+2√2)] -2*1/(3-2√2)*1/3+2√2)

=[3+2√2+3-2√2]-2*

=6-2=4

3)

=√x + 1/√x

=(x+1)/√x

putting the value of x=7+4√3

=(7+4√3+1)/√(7+4√3)

=(8+4√3)/√(7+4√3)
