Rewrite question.
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.

they could depend on each other so they asked each other to give them some power.
