Question

multiple-choice question
what is the last step to solve for c?
multiply both sides by 2.
take the square root of both sides.
divide both sides by 2.

Explanation:

To solve for \( c \) (likely in a context like the Pythagorean theorem \( a^{2}+b^{2}=c^{2} \)), after isolating \( c^{2} \), the last step is to take the square root of both sides to solve for \( c \). Multiplying or dividing by 2 is not the final step for solving for \( c \) in such a typical equation.

Answer:

Take the square root of both sides.
