Question

In scientific notations, (6.2x10^4) x (3.3x10^2) equals

Answer 1

the answer is 20460000

Answer 2

`2.0*10^(7)`

Step-by-step explanation:

Give the answer in scientific notation means that you should give the answer in a simplified way.

For example:

`62000=6.2*10^(4)`

`330=3.3*10^(2)`

The number above the ten is called the exponent and tells you how many times you need to displace the decimal point.

If you multiply, first you shoud multiply the two numbers, then you should add up the exponents of the number ten for each quantity you have, in this case:

`(6.2*10^(4)).(3.3*10^(2))=20.46*10^((4+2))`

Finally you add up the exponents:

`(6.2*10^(4)).(3.3*10^(2))=20.46*10^(6)`

And you should give the answer with only one decimal, so:

`(6.2*10^(4)).(3.3*10^(2))=2.0*10^(7)`
