Easy.
Say I was going to do
____
\/ 2 =1.41....
So then you square the left side
2=1.41....
And then you square the other side
2=2
(When you square root a number and you square it, you end up with the original number)
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
Take the square root of both sides of the equation
To solve a square root equation, first isolate the square root term on one side of the equation. Then, square both sides to eliminate the square root. After squaring, solve the resulting equation for the variable. Finally, check your solutions to ensure they are valid, as squaring can introduce extraneous solutions.
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.
To solve a square root math puzzle, first identify the expression or equation that contains the square root. Simplify the equation if possible by isolating the square root on one side. Then, square both sides of the equation to eliminate the square root, and solve the resulting equation for the variable. Finally, check your solution by substituting it back into the original equation to ensure it satisfies the condition.
facctor the problem and atke the square root of both sides
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
Since the area equals pi times the square of the radius, the radius must be the square root of (the area divided by pi). I got that by dividing both sides of the equation by pi then taking the square root of both sides.
A = pi * r2, so by dividing both sides of the equation by pi then taking the square root of both sides, you get... r = (A/pi)½ (r equals the square root of the quotient of A divided by pi.)
take the square root of both sides.
y2 = 169 Square root both sides: y = 13
x2 = 81 Square root both sides:- x = +/- 9
