Question

if root (10 -6 root 5) = a + b, then find a+b and ab

Answer 1

$\sqrt{10 - 6 \sqrt{5} } = a + b$

Answer 2

10 - 6 root5 = a + b

Therefore, a=10
& b = -6 root5

as now we know the value of a and b

so we can also find ab, by putting the value of a and b e it

ab = 10 X -6 root5
an = -60 root 5
