In an up-and-down counting number, the digits increase to a maximum digit and then decrease. This maximum is not the first or last digit. (Example:
2S68S0 is an up-and-down number, but 25587 6 is not.) How many different
4-digit up-and-down numbers have a maximum digit of 6?

just sum

10 + 10 = 20

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

=240

=48
