·Herbivores have wide, flat teeth for grinding leaves, grasses and other plants·The front of the Herbivores incisor is made of a stronger materials than the back of the incisor·Goats are examples of herbivores
Exponents
·exponents can be used to show repeated multiplication; 25 = 2 * 2 * 2 * 2 * 2·a power has two parts·a base and an exponent·the expression 32 is read "three to the second power

Examples
1. 5 * 5 * 5 = 53
2. (-3)(-3) = (-3)2 read as negative three to the second power
Write the expression using exponents.
1. 4 * 4 * 4 43
