Answer:
193.8
Step-by-step explanation:
a = 3.8 times 10^13 = 38,000,000,000,000
b = 5.1 times 10^-12 = 0.0000000000051
a times b = 193.8

Scientific notation is a special way we choose for writing numbers. So the numers
are written in scientific notation. In this way, we have a quotient of two numbers written in scientific notation. To solve this problem, we have:
![\frac{6.47}{3.36}\times 10^{[-15-(-29)]}=1.92559524\times 10^{(-15+29)} \\ \\ \therefore 1.92559524\times 10^{14} \ or \ \boxed{1.92559524e+14}](https://tex.z-dn.net/?f=%5Cfrac%7B6.47%7D%7B3.36%7D%5Ctimes%2010%5E%7B%5B-15-%28-29%29%5D%7D%3D1.92559524%5Ctimes%2010%5E%7B%28-15%2B29%29%7D%20%5C%5C%20%5C%5C%20%5Ctherefore%201.92559524%5Ctimes%2010%5E%7B14%7D%20%5C%20or%20%5C%20%5Cboxed%7B1.92559524e%2B14%7D)
The division has been performed using the rules for operation with exponentiation.
Answer:
is the nth term of the given sequence.
Step-by-step explanation:
The sequence given is

We can clearly see that 1st term is
and 2nd term is
2nd term is obtained by multiplying the 1st term by 2.
2nd term is
and 3rd term is 1.
3rd term is obtained by multiplying the 2nd term by 2.
3rd term is 1 and 4th term is 2.
4th term is obtained by multiplying the 3rd term by 2.
Clearly, the given series is a <em>Geometric Progression(GP)</em> with
First term, 
Common Ratio,
We know that
term for a GP is:

Putting values of <em>a</em> and <em>r</em>

Hence,
is the nth term of the given sequence.
It would be between 2.77 and 2.79
