answer in full

Answer 1

Step-by-step explanation:

Please check the solution and ask if any step is not clear.

Answer 2

Step-by-step explanation:

√7-2/√7+2=a√7+b

(√7-2/√7+2)*(√7-2/√7-2)

(√7)square - 2(√7)(2) + (2)square/(√7)square - (2)square

7-4√7+4/7-4

11-4√7/3 = a√7+b

we can write 11-4√7/3 as -4√7/3+11/3

so, a=-4√7/3 and b=11/3

above is your answer

if it's correct so pls mark me as brainlist.
