Using the formula for  permutation, there are 5040 ways that  7 objects are taken 1 at a time.

What is permutation?

The permutation of objects refers to the number of ways that an object can be selected from a number of objects.

Given that;

nPr = n!/(n - r)!

Hence;

7P1 = 7!/(7 - 1)!

7P1 = 7 * 6 !/6!

7P1 = 7 * 6 * 5 * 4 * 3 * 2 *1

7P1 = 5040
