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
Oh, dude, the square root of x plus the square root of y is just that - the square root of x plus the square root of y. It's like adding apples and oranges, you can't really simplify it further. So, like, that's your answer, no need to overcomplicate things, man.
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.
