E=mc2 is one of the most recognizable equations in the world. in this task, you’ll attempt to understand it better. let’s start with what the letters mean. the letter e stands for energy, the letter m stands for mass, and the letter c stands for the speed of light. the meaning of this equation is that you can completely convert mass into energy.
rewrite the equation to solve for the speed of light, c. use rational exponents instead of roots.

i dont know

step-by-step explanation:

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2  

x

2  

x

​    

=240

=48
