<span>(4.7 x 10^4) by (6.4 x 10^15)

4.7 * 6.4 = 30.08
10^4 * 10^15 = 10^19

so
</span>(4.7 x 10^4) by (6.4 x 10^15)
= 30.08 x 10^19
= 3.008 x 10^20

Find the sum of the following series. Round to the nearest hundredth if necessary,

Aneli [31]

Answer:

$sum = \frac{a( {r}^{n - 1} )}{r - 1} \\ : but \: l = a( {r}^{n - 1} ) \\ 49152 = 3( {2}^{n - 1} ) \\ 16384 = {2}^{n - 1} \\ {2}^{n} = 32768 \\ {2}^{n} = {2}^{15} \\ n = 15 \\ \therefore \: sum = \frac{3(2 {}^{15 - 1}) }{15 - 1} \\ = \frac{49152}{14} \\ = 3510.9$
