Question

What is the solution to the equation? n = 2 n = 4 n = 7 n = 14

Answer 1

n=2

Explanation:

got it right on edge

Answer 2

n = 2

Explanation:

`√(2n+28)-4√(n)=0\\\\\\√(2n+28) = 4√(n)\\\\`

Take square,

`(√(2n+28))^(2)=( 4√(n))^(2)\\\\ 2n + 28 = 16n\\\\28 = 16n -2n\\\\28 =14n\\\\14n=28\\\\n=(28)/(14)\\\\n=2`
