·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

Factors

·one integer divides into another number with a remainder of zero·example: factors of 6 are 1, 2, 3,

List the positive factors of:

1. 10 1, 2, 5, 10

2. 21 1, 3, 7, 21

3. 24 1, 2, 3, 4, 6, 8 ,12 ,24

·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

2. 3 * 3 * 3 * 3 * 3 35
