Question 208008: Please help me solve these problems! Could you tell me if I have the right answers for below???
Multiply and simplify.
5^16*5^24=5^-8
Divide and simplify.
(6v)^9 1
(6v)^14 = 6t^5
Multiply.
(y^2-8)(3y^2-6y+4)
=3y^4 - 6y^3 - 20y^2 +48y -32
Thank you very much!!!

Multiply and simplify.
5^16*5^24=5^-8
-------------
5^16*5^24=5^(16+24)
= 5^40
------
Divide and simplify.
(6v)^9 1
(6v)^14 = 6t^5
--------------
If you mean
%28%286v%29%5E9%29%2F%286v%29%5E14
= %286v%29%5E%289-14%29
= %286v%29%5E-5 or
= 1%2F%286v%29%5E5
---------------
Multiply.
(y^2-8)(3y^2-6y+4)
=3y^4 - 6y^3 - 20y^2 +48y -32
Looks right to me.
