Question

How many times larger than
`(2 * {10}^(7) )is(8 * {10}^(15) )`write your answer in scientific notation

Answer 1

We have to find how may times larger than 2*10^7 is 8*10^15.

We can find this by dividing 8*10^15 by 2*10^7:

`k=(8\cdot10^(15))/(2\cdot10^7)=(8)/(2)\cdot(10^(15))/(10^7)=4\cdot10^((15-7))=4\cdot10^8`

Answer: 4*10^8 times bigger.
