POWERS or INDICIES
State what a root is
The root of a number in math is a number that when multiplied by itself produces the original number. For example, the square root of 49 is 7 because 7×7=49. In this case, because 7 is multiplied by itself twice to produce 49, we call 7 the square root of 49. The cube root of 27 is 3, because 3×3×3=27.
Define what a liner graphy is or looks like
