Solve for xx. Express your answer in simplest radical form if necessary.
x^2=81
To solve for x in the equation x^2 = 81, we can take the square root of both sides:
√(x^2) = √81
This simplifies to:
|x| = 9
So x can be either positive or negative 9.
tell me what the answer is pleaee
The answer is x = ±9.
so X=9 ?
No, the correct answer is x = ±9. This means that x can be either positive 9 or negative 9. Both solutions satisfy the equation x^2 = 81.
what does that mean it is not postitive or negative
When we say x = ±9, it means that x can be either positive 9 or negative 9. In other words, both values of x satisfy the equation x^2 = 81. So, the solution to the equation x^2 = 81 is x = 9 or x = -9.
