Basics of Radicals
The solution to
What is x=16?
The reason has no real solution.
What is a square root cannot be a negative?
The value of x in:
What is x=3?
written as a fractional exponent.
What is x^5/3?
The first step to solve
What is add 7 to both sides?
Solving gives x=3 and x=-2. This answer is extraneous.
What is x=-2?
The value of x in:
What is x=5?
The value of x in:
What is x=81?
Solving results in this value of x.
What is x=16?
The potential but invalid solution for
What is x=14?
The value of x in:
What is x=8?
The simplified version of the expression:
What is 3x^2?
To solve you must raise both sides to this power.
What is the 4th power?
Solving leads to these two potential values, but only x=9 works.
What are x=-9 and x=2?
The value of x in:
What is x=4?
The value of x in:
What is x=-2? (Note: Cubic roots can result in negatives.)
The value of x in
What is x=8?
True or False: Squaring both sides of an equation can sometimes create "fake" solutions.
What is True?
The value of x in:
What is x=2? (x=-2 is extraneous)
The value of x in:
What is x=7 and x=9? (Note: You must consider both positive and negative roots here.)
