Question

Solve:√(7+2√6) - √(7-2√6) = ?​

Answer 1

Step-by-step explanation:

43–12.(7)^1/2=(6)^2+(7^1/2)^2–2×6×(7)^1/2

= ( 6–7^1/2)^2

16+6.(7)^1/2= (3)^2+ ( 7^1/2)^2+2×3×(7)^1/2

=( 3 + 7^1/2)^2. Now

[43–12.(7)^1/2]^1/2 - 2 /[16+6.(7)^1/2]^1/2

=(6–7^1/2) - 2 /(3+7^1/2)

=(6–7^1/2) - 2×(3–7^1/2)/(3+7^1/2)(3–7^1/2)

=(6–7^1/2)-2×(3–7^1/2)/(9–7)

=6–7^1/2–3+7^1/2

=3 , Answer.

Answer 2

Bro answer is zero

Step-by-step explanation:

$\sqrt{(7 + 2 \sqrt{6)} } - \sqrt{(7 - 2 \sqrt{6)} } \\ = 0$
