Rearrange the product

(5.91 * 10^(-3)) * (8.7 * 10^10)

(5.91 * 8.7) * (10^(-3) * 10^10)

We have 5.91 * 8.7 = 51.417, and 10^(-3) * 10^10 = 10^(10 - 3) = 10^7, so the original product above reduces to

51.417 * 10^7

We can "add" powers of 10 by moving the decimal place to the left:

51.417 = 5.1417 * 10

so that

51.417 * 10^7 = (5.1417 * 10) * 10^7 = 5.1417 * 10^8

Identify the 12th term of a geometric sequence where a1 = 8 and a6 = −8,192.

vodka [1.7K]

Geometric sequence
$a_{n}=a_{1}*r^{n-1}$
r=common ratio
a1=first term
find r

a1=8
a6=-8192
$-8192=a_{6}=8*r^{6-1}$
$-8192=8*r^{5}$
divide both sides by 8
$-1024=8*r^{5}$
take 5th root of both sides
-4=r
sub
$a_{12}=8*(-4)^{12-1}$
$a_{12}=8*(-4)^{11}$
$a_{12}=8*-4194304$
$a_{12}=-33554432$

The answer is 12+3r because 4 times 3=12 then the 3r which you cannot add because they are no others variables that are r
