Can someone me with this? i need answers quick! write the following expressions in simplified form. 1) 5^-1 2)3^-3 3) 4^4/4 4) 8^4/8^0 5) (-4)^8/(-4)^4 6) g^9/g^15 complete the following equations. 1) 1/3^5 = 3^? 2) 1/-125 = (-5)^? 3) z^? /z^8 = z^-3 is each statement true or false? explain your reasoning. (-1)^3 = 1^-3

In the future, would you please post just one or two problems at a time.  Be fair to others who also want help.

#5:     (-4)^8/(-4)^4 can be expressed more clearly as     (-4)^8
                                                                                         
                                                                                           (-4^4)

and this can be reduced to (-4)^4    by subtracting the exponent 4 from the 
                                                         exponent 8.

furthermore, because of the even exponent, (-4)^4 can be written as 4^4.

Note that 4^4 = (4^2)^2 = 16^2 = 256 (answer)
