Sym Ops 1 Homework Solutions Simplify by performing the appropriate operation 1. 3 x 2 5 x 2 Since these are like terms, they can be combined by adding (subtracting) their coefficients. 3 x 2 5 x 2 =− 2 x 2 2. 8 x 2 y 2 x 2 y + 4 x 2 y Since all three terms are like terms, they can be combined by adding (subtracting) their coefficients. 8 x 2 y 2 x 2 y + 4 x 2 y = 10 x 2 y 3. x 3 y 2 2 xy + 4 x 3 y 2 Only two of the terms are like terms. They can be written as a single term. x 3 y 2 2 xy + 4 x 3 y 2 = 5 x 3 y 2 2 xy 4. 4 x 2 2 x 2 Any two terms can be multiplied. Multiply the coefficients. When you multiply variables of the same base, add their exponents. 4 x 2 2 x 2 = 8 x 4 5. 5 x 3 3 x 4 Any two terms can be multiplied. Multiply the coefficients. When you multiply variables of the same base, add their exponents. 5 x 3 3 x 4 15 x 7 6. x 3 3 x 2 4 x 2 y Any number of terms can be multiplied. Multiply the coefficients. When you multiply variables of the same base, add their exponents.
