A clock has sixty minutes for every one rotation. One full rotation has 360°. Knowing this, we can set up a ratio:
\frac{60min}{360} = \frac{6min}{36} =  \frac{1min}{6}
So, for every 1 minute, a clock hand moves 6°.

Next, all we have to do is multiply the number of minutes by 6°:
9min*6degrees=54degrees \\ 35min*6degrees= 210degrees \\ 45min*6degrees=270degrees

So:
In 9 minutes, a clock-hand moves 54°
In 35 minutes, a clock-hand moves 210°
In 45 minutes, a clock-hand moves 270°

Hope this helps!

subtract the exponents but leave the base alone to get 5⁴.

We can also write 5⁴ as 5 · 5 · 5 · 5.
