Exercise 54 Page 70

Use the rules for the sum of exponents to simplify the expression.

x^n (x^6+x^2+1)

Practice makes perfect

We can use the rules for the sum of exponents to help us factor this expression.

x^(n+6)+x^(n+2)+x^n

a^(m+n)=a^m*a^n

x^n x^6+x^n x^2+x^n

Factor out x^n

x^n (x^6+x^2+1)
