9.4 Multiplying and dividing Rational Expressions

Simplify the expressions                                                                                   

Ashley a.

1) 6f³ (f⁴ b⁶ k¹⁰) = 6f⁷ 6b⁶ 6k¹⁰    The 6 has to be distributed. In other words 
                                                                 multiplied by everything in the parenthesis.

2)A) 16a⁵c⁷f¹⁸                            The fs cancel out. You can reduce the 16

         4h⁴m²f¹⁸                             and 4 which leaves a 4 on top. The end.

B)4a⁵c⁷

    h⁴m²

3)A) 30j⁵h⁸l^{2                          To make things easier for yourself you should}    

             5j³h⁵l                             separate the fraction
         20k⁷a⁷e²

             6k⁸a⁶e⁵

B) 30j³h⁵l²       (6k⁸a⁶e⁵)          After you separate the fraction flip the 

     5j³h⁵l          (20k⁷a⁷e²)     bottom one so you can times the fractions 
                                                                                                           together      

C) 6l   (3ke³)                      Now simplify it into the simplest form

              10a

D)18e³kl                       You are still not done. 10 and 18 can be divided by 2   

       10a                          

E)  9e³kl                                YOU ARE DONE!

       5a
