How do you do square root math problems?
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.
What is 46x X 87y over the square-root of 90?
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
What is the most challenging math equation in the world?
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.
How do you solve 9x squared x 81?
9x2 = 81 x2 = 9 <-- Divide both sides by nine x = 3 <-- Square root both sides All in all this is NOT a difficult equation.
What is the square of the sum of a number and 4 is 36?
(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
Which is the best way to solve the equation x2 equals n?
Take the square root of both sides of the equation

What are some ways to solve an quadratice equation?
facctor the problem and atke the square root of both sides

How do you determine the radius of a circle if you have the area?
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.
How do you convert area back to radius?
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.)
What would be the most logical first step to solve this quadratic equation?
take the square root of both sides.
What are the solutions to the equation y2 equals 169?
y2 = 169 Square root both sides: y = 13
What are the solutions to the equation x2 equals 81?
x2 = 81 Square root both sides:- x = +/- 9

What is the square root of 2x plus 1 equals 3?
The answer will depend on how far the square root sign goes.If you want to solve for "x", I suggest you isolate the square root on the left (if it only covers the "2x" part, move the "1" to the other side of the equation). Then, if you square both sides of the equation, you get a formula which you can easily convert to a form which can be solved with the quadratic equation.
How do you find the radius if you know the area?
The area of a circle is given by the equation A=πr2.To solve for r, divide both sides by π, then take the square root of both sides of the equation.This leaves you with the equation r=sqrt(A/π)
