The easiest way I know is to always remember that number line. Negative numbers are always to the left and positive numbers are always to the right of "O" (zero).
Numbers are always represented by its first point or position. For example lets look at the number 268000000. The first position is the number "2" and its appears (because theres no deicmal point or minus sign) that this is a positive number. So we start at the 2 and count the number of numbers after the 2 which is 8. So to write this number as an exponent we would say 268000000 is the same as saying 2.68x10 to the 8th power.

6.50 x 10^3 years
Multiply the base by square root of 10 to the 4th power then divide by 2! (factorial) times 10!
A 10-20 vdc power source is a low output power supply used for small devices like battery chargers, notebook computers, and appliances. They use AC power input to convert it into DC power.
you x it by 10 to the power of -6 as mm is already 10-3 so to get to nm which is 10 -9 you would have to x by 10-6
6.4 × 10⁶ = 6.4 × (10 × 10 × 10 × 10 × 10 × 10) = 6.4 × 1,000,000 = 6,400,000 To convert standard form (aka scientific notation) to standard notation move the decimal point the same number of digits as the power of 10 to the right if the power is positive and to the left if the power is negative, inserting 0s if you run out of digits.

It IS a whole number!

3.78 x 10 to the power -2
1.5 times 10 to the power of 2
6.50 x 10^3 years
1.86 times 10 to the 5th power
Multiply the base by square root of 10 to the 4th power then divide by 2! (factorial) times 10!
you times milligrams by 0.0000001 or 10 to the power of -6 mg*0.0000001=kg
The answer is 88 moles.

To convert a number to scientific notation we first need to divide that number by a power of 10 such that the answer has units as its greatest place value. In this case we can divide by 0.0000001 to get 8. The next step is expressing the number divided by as a power of 10 alongside the number in a multiplication. 0.0000001 is the negative 7th power of 10, or 10-7. Therefore, 0.0000008 in scientific notation is 8x10-7
