Multiplying and Dividing Monomials

Multiplying and Dividing Monomials

Example 1

Find 5z3* 6z2.

Multiplying and Dividing Monomials

Example 1

Find 5z3* 6z2.

5 * 6 = 30 FIRST MULTIPLY NUMBERS

z3* z2 =z3+2 = z5 THEN MULTIPLY VARIABLES

Multiplying and Dividing Monomials

Example 1

Find 5z3* 6z2.

5 * 6 = 30 FIRST MULTIPLY NUMBERS

z3 * z2 =z3+2 = z5 THEN MULTIPLY VARIABLES

Check: z3* z2 = (z*z*z)*(z*z) = z*z*z*z*z = z5
