A bar of length it coincides with the interval [0, 1] on the x-axis. Set up the boundary - value problem for the temperature u(x, t)
if the left end is held at temperature 0°c and the right end is held
at temperature 60°C fo all time. The initial temperature of the bar
is sin(21x) throughout.​

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
