Answer:a=0, b=1
Step-by-step explanation:
Rationalising both the numbers that are: 7 +√5/ 7-√5 and 7-√5/7+√5.
Solving it.
Comparing:
when we get 7 upon 11 root 5 is start comparing a + 7 upon 11 root 5 into b.since we can't see a therefore we put the value of a = 0 as well as we can't see be but we put its value one because it is multiplying by root 5 and root 7 upon 11 and if we put the value = 20 of b then whole will be zero that's why we will put the value of b equals to 1.
