Item 15
the lowest altitude of an altocumulus cloud is about 3838 feet. the highest altitude of an altocumulus cloud is about 3 times the lowest altitude. what is the highest altitude of an altocumulus cloud? write your answer as a power.

The right question is that the lowest altitute is 3^8 feet

You are told that the highest altitude is 3 times the lowest altitude =>

highest altitude = 3 * lowest altitude = 3 * 3^8 feet.

Now you use the ruel of mutiplication of powers with the same base: copy the base and sum the exponents => 3 * 3^8 = 3 ^(1+8) = 3^9.

Note: remember that 3 = 3^1.

3^9 feet
