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
The expression, 0.261 is referred to as a decimal fraction. To convert it to an ordinary fraction multiply it by the relevant power of 10 to convert it to a number with NO portion AFTER the decimal point, put the relevant power of 10 as the denominator and see if the fraction can be simplified. 0.261 = 0.261 x 1000 / 1000 = 261/1000

It IS a whole number!

3.78 x 10 to the power -2
1.5 times 10 to the power of 2

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.

You convert by writing the numerical of a quantity as a number between 1/10, multiplied by a whole number power of 10 example M x 10n m = the multiplier 10= the whole number n = the exponent
To convert power in watts to decibels (dB), you can use the formula: dB = 10 * log10(P2/P1), where P1 is the reference power (usually 1 watt) and P2 is the power you are converting (40 watts in this case). Plugging in the values, you would calculate: dB = 10 * log10(40/1) = 16.02 dB.
