7.74x10^-4

1 answer

All you need to remember with scientific notation is the decimal place and the number of 10's to the left (-) or right (+) from the decimal.

For instance if the number is 5.14*10^5
multiply the coefficient or base (5.14) by the power of 10, in this case five. In this case the 0s go to to right of the decimal. You need to remember to put an extra zero and decimal at the end of the 0s.
5.14x10^5 is 5.14x10x10x10x10x10 5.14000.0.
If the power is ^-5 it would be
0.00005.14
Does that make sense?
Basically a scientific notation is converting the expression into whole numbers.
