∙ 10y agoIf you take the square root of any number (or expression) and then square the result again, you will usually obtain the same number (or expression) again. Or more precisely, its absolute value. That is, sometimes you can make the simplifying assumption that you get the same expression, but to be on the safe side, you must consider the possibility that the original expression is negative, in which case the square of the square root is the absolute value of the original expression.

What is square root 78 then squared in surd form?
[square root (78)] squared = 78. There is not a surd from for an integer.
What is the square root of 8 squared?
Do you mean: What is the square root of (8 squared)? If so, there are two answers: 8 and -8. Or do you mean: What is the (square root of 8) squared? If so, there is only one answer: 8.
X squared Times Square root of x?
: x squared times square root of x : : = x^2 * x^(1/2) : = x^[2+(1/2)] : = x^[(4/2)+(1/2)] : = x^(5/2) : which is the same thing as : square root of (x raised to the 5th power)
What is the square root of 24 x to the third and y to the forth?
2x square root 6x y squared
What is the solution of X squared - 2X - 2 equals 0?
1 +/- the square root of 3
What is 2x divided by x squared?
You should square root both the top and bottom of the equation, which would give you (√2x)/x.
What is half x squared equals x?
is (x^2)/2=x then (x^2)=2x then x=square root of (2x)
The length of a rectangle is five feet more than twice its width and the area of the rectangle is sixty-three Find the dimensions of the rectangle?
Let the width = X. The length is twice the width plus 5. So the length must be 2X + 5. Area = 63 ft squared = X multiplied by 2X + 5 = 2X squared + 25. 2X squared = 63 - 25 = 38 2X = square root of 38. Therefore the width is the square root of 38 divided by 2 and the length is the square root of 38 plus 5.
What is the integral of -2x divided by the square root of x squared minus 4?
- ln ((x^2)-4)
What is the answer to the square root of 2x-15-x6?
I think you've left out something. Is one of the "x" functions squared?
What is the square root of four x squared?
The square root of 4x^2 is solved by first doing the square root of 4. This is plus or minus two - because -2 x -2=4. The square root of x^2 is x. So the answers are 2x or -2x. If your question was (4x)^2, then the answer would be 4x.
What is the square root of A squared?
The square root of A2 is... A !
Justify each step which are conjecture 2x 2 equals 50?
If you mean: 2x squared = 50 Divide both sides by 2: x squared = 25 Square root both sides: x = 5
