Question

I need help. In MATH, (not science) i have an equation. The equation is E=mc^2 , solve for c. i am lost

Answer 1

Given the equation:

$E=mc^2$

To solve for c.

First step:

Divide both sides by m

$\begin{gathered} \frac{E}{m}=\frac{mc^2}{m} \\ \\ \frac{E}{m}=c^2 \end{gathered}$

Second step:

Take the square root of both sides

$\begin{gathered} \sqrt[]{\frac{E}{m}}=\sqrt[]{c^2}^{} \\ \\ \sqrt[]{\frac{E}{m}}=c \\ \\ c\text{ = }\sqrt[]{\frac{E}{m}} \end{gathered}$

ANSWER:

$c\text{ = }\sqrt[]{\frac{E}{m}}$
