How do you simplify a square root of a product?

Back

To simplify a square root of a product, you can separate the square root into the product of the square roots of each factor: √(a*b) = √a * √b.

What is the square root of a variable raised to an even power?

Back

The square root of a variable raised to an even power is the variable raised to half that power: √(x^2n) = x^n.

What is the square root of a variable raised to an odd power?

Back

The square root of a variable raised to an odd power can be simplified by separating the variable into an even and an odd part: √(x^(2n+1)) = x^n * √x.

How do you simplify √(a^2)?

Back

√(a^2) simplifies to |a|, which is the absolute value of a.

Front

What is the process for simplifying √(ab)?

Back

To simplify √(ab), you can express it as √a * √b, provided both a and b are non-negative.
