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 of 4x is 2 times square root of x, so answer is square root of x times 3 since it is 2 square roots of x plus one of them
5 - x^2 = (the square root of 5 minus x)(the square root of 5 plus x)
It depends entirely on the value of x.
That expression can't be simplified. It has to written, and evaluated, just as it appears in the question: [ sqrt(x + 2) ] + [ sqrt(x + 3) ]
x=16
X^1/2 + Y^1/2 Essentially it is just the square root of x plus the square root of y, there's no real way of simplifying that.
Yes (x+3(x+3)
if x is equal to the square root of 81 then x is ±9 (plus or minus 9)
x = 7
what is the domain of g(x) equals square root of x plus 1? √(x+1) ≥ 0 x+1≥0 x≥-1 Domain: [-1,∞)
It is an expression, in a variable x. Since it is not an equation, it cannot be solved.
