That will obviously depend on the specific problem. If you have an equation with a variable under a square root sign, it often helps to square both sides of the equation.
If you move that 46x over the equals, and if you square both sides, you can get rid of that square root, and do the equation normally. do the math
46x by 87y -------------- √ 90 Tips: If you move that 46x over the equals, and if you square both sides, you can get rid of that square root, and do the equation normally.
9x2 = 81 x2 = 9 <-- Divide both sides by nine x = 3 <-- Square root both sides All in all this is NOT a difficult equation.
(n+4)2 = 36 This is your equation. To solve for it square root of both sides then minus the 4 from both sides and you find your "n" n+4= 6 n=2 Your variable equals 2
