What does -2 raised by 10 equal to?

I think "raised by ten" is trying to say add 10. So for this you would write an expression based on the information provided.

-2 + 10 = ?

A simple way to solve this problem would be to switch the numbers. Now this only applies to this situation where the negative number is before the positive number.

10 + (-2) = ?

Now you will just take out the addition signs and keep the minus.

10 - 2 = 8

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
