Write the following
number in scientific
notation.
.00078

7.8 × 10^-4

Step-by-step explanation:

Although this answer is perfectly O.K., most commonly the base, or the 0.00078, is written as a number with just one digit to the left of the decimal.

To format your number in this way, we'll multiply the .00078 by 10, 4 time(s), making it a 7.8.

We do this, because each multiplication by 10 moves the decimal point to the right one digit.

But in order to keep our number the same number, we must have a × 10-4 next to the 7.8.

So, the final answer is 7.8 × 10^-4

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled
