Question

1 bar root 9-root 8 is equal to

Answer 1

Answer:

3+root8

Step-by-step explanation:

1/root9-root8

simplify these with rationalization

multiply num. and den. with terms in den. of original fraction with a sign change in between

i.e

(1/root9-root8) * (root9+root8/root9+root8)

=root9+root8/(root9^2-root8^2)  (we used formula (a+b)(a-b)=a^2-b^2  )

=root9+root8/(9-8)

=root9+root8

=3+root8
