Question

if a is equals to root 7 minus root 6 upon root 7 + root 6 and b is equals to root 7 + root 6 upon root 7 root minus root 6 then find the value of a b square + A B

Answer 1

a=root 7 - root 6 / root 7+root 6
a square =1 / 13 , and, a=root 1/13

Now, b= root 7+root 6 / root 7 - root 6
=b square = 13
=b=root 13

Now, ab square +ab= root

Now, eq1-eq2.
