x=2
22=6-2
4=4
Nop! Square root of x - not x squared!
sqrt(x) = 6 - x => |x| = (6 - x) * (6 - x) <=> |x| = 6 * 6 - 12 * x + x * x =>
=> x = 9.
If x equals the square root of ...., then you already have solved for x
Plus or minus the base. If the base is X and you square it, you get X2. If you take the square root of that, you get Plus or Minus X. This is because X*X equals X2 and -X*-X also equals X2.
square root -5 minus 14 or - square root -5 minus 14
square root of 8
The square root of 400 is 20, as 20 multiplied by 20 equals 400. The square root of 196 is 14, as 14 multiplied by 14 equals 196. Therefore, the expression simplifies to 20 - 14, which equals 6.
Yes and x = 2+square root of 6 or x = 2-square root of 6

In order to represent the square root of a minus number (which does not in fact actually exist other than as an abstract notion), mathematicians use an imaginary number called "i". i represents the value of the square root of -1. We must remember that it is not a real number, which is why we call it imaginary.So to answer your question, i, or a multiple of i, times itself equals a minus number.For example 2i * 2i = -4 (this is because we can rewrite -4 as 4 * -1. The square root of 4 is 2 and the square root of -1 is i. Therefore the square root of -4 is 2i).
The square root of minus 8 is equal to the square root of 8 times the square root of minus 1, or 2.8284i.
The square root of a value v is a number x such that, x multiplied by x equals v. Note that -x is also a square root.
pi it's so easy
