Question

If 9 + 5√5 = a - b√5 then value of a +b is:​

Answer 1

Answer:

4 will be the answer of your question:

Step-by-step explanation:

$9 + 5\sqrt{5} = a - b\sqrt{5}$

on compairing both sides:

we have ,

      a = 9

and, $-b\sqrt{5} = 5\sqrt{5}$

then, b = -5

therefore, a = 9 and b = -5

and a + b = 4
