Answer 2

Answer:

1/3-root7

multiply the whole 1/3-root seven with 3+root7/3+root seven

you will get 3+root7/3-root7 × 3+root 7

now express the denominator in a square-b square formula

keep the numerator same. you will get the denominator as 3 the whole square - root 7 the whole square

3^2=9 and root 7 the whole square is 7

so then subtract 9 and seven you will get 2

the numerator remains the same

so the final answer is 3+root7/ 2
