What is the second power?

Answer 1

When you multiply a number by itself, you get the "second power" of the number.
That's also called the "square" of the number.

Here are some examples:

The second power of 5 is (5 x 5) = 25.

The second power (square) of 10 is (10 x 10) = 100.

The square (second power) of 6 is (6 x 6) = 36.

The square of 3.1 is (3.1 x 3.1) = 9.61.
