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

#5:     <span>(-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)</span>

What is the explicit formula for the sequence 3, 7,
balu736 [363]

Answer:

an = 4n - 1

a1 = 3

a2 = 7 = 3 + 4

a3 = 11 = 3 + 4.2

a4 = 15 = 3 + 4.3

a5 = 19 = 3 + 4.5

.....

=> this is a arithmetic with a1 = 3 and d = 4

=> an = 3 + 4(n - 1) = 4n - 1

kow [346]
The first thing we need to know is that the Jennifer-Chelsea ratio is as follows:
 3: 2
 Equivalently:
 3/2
 To know how much Jennifer invests, we have to:
 (3 / (2 + 3)) = x / 125000
 Clearing x:
 x = 125000 * (3 / (2 + 3)) = 75000
 answer
 Jennifer invest 75000 $
