For questions 3 and 4, simplify each expression.

3) 4^4/4^6

4) 5^0

For questions 6-8, multiply the following polynomial.

6) -2r( 8r + 5 )

7) 4a( a^2 + 7a + 4 )

8) ( 2y - 3 )( 3y - 2 )

For questions 1 and 2 , write each expression using a single exponent.

[tex]1) \ x^9:x^2=x^7\\ \\ 2) \ h^{14}:h^{5}=h^9[/tex]

For questions 3 and 4, simplify each expression.

[tex]3) \ 4^4:4^6=4^{-2}=\frac{1}{4^2}=\frac{1}{16}\\ \\ 4) \ 5^0=1[/tex]

For questions 6-8, multiply the following polynomial.

[tex]6) \ -2r(8r+5)=-16r^2-10r\\ \\ 7) \ 4a(a^2+7a+4)=4a^3+28a^2+16a\\ \\ 8) \ (2y-3)(3y-2)=6y^2-4y-9y+6=6y^2-13y+6[/tex]
