Today in class we've revised the four properties that ''

25 · 43 = 25 · (22)3 = 25 · 26 = 211

c) When you finish a negative operation and the exponent that is raised to is even the base converts in positive. If it is odd it keeps negative.

Example: (-9)6 : (-9)2 = (-9)4 = 94
-(-2)3 = 23 = 8

Those where the three things we have to have in mind when we are operating.

even: that number that you can divide it by two (par)
odd: That number that you can't divide it by two (impar)

Something interesting: look all the things you can obtain with the pieces of a cube
