Answer:
x = +√30
Step-by-step explanation:
Please write 30 = x squared as 30 = x^2.
If x^2 = 30, there are two solutions: x = +√30 and x = -√30.
Several possible answers are given. x=30−−√ is closest to the correct one, but must be written as x = √30. Please ask someone how to find the "√" operator in Brainly. Or, just write "sqrt( )" instead.
