Answer:
Step-by-step explanation:
Start with this equation where 17 is the base, x is the power that 17 must be raised to. Then 2 is the result.
17^x = 2 Take the log of both sides
log(17^x) = log(2) Take the x outside the brackets
x log(17) = log(2) Divide by log 17
x = log(2)/log(17) Find the values for log 2 and log 17
log(2) = 0.3010
log(17) = 1.230
x = .3010/1.230
x = .2446

I HOPE IT WILL HELP YOU A LOT.
Have a great day ahead.
We must find the common ratio first...
Since a(n)=ar^(n-1)
-3359232=12r^7
-279936=r^7
-279936^(1/7)=r
-6=r
So our geometric sequence is:
a(n)=12(-6)^(n-1)
And the sum of a geometric sequence is:
s(n)=a(1-r^n)/(1-r), since a=12, r=-6, and n=8 we have:
s(8)=12(1-(-6)^8)/(1--6)
s(8)=12(1-(-6)^8)/7
s(8)= -2,879,340
