How many three-digit numbers can be formed from 32564 without repeating any of the digits?

The mean of a set of six numbers is 60. If the mean of the first five is 50, find the sixth number in the set.

Calculate the mean deviation of the set of numbers 7, 3, 14, 9, 7, and 8.

Evaluate \(Log_{\sqrt{2}}4 + Log_{\frac{1}{2}}16 - Log_{4}32\)

Simplify 213\(_4\) x 23\(_4\)
