You add one more zero to the end of the number
Move the decimal point to the right one time.
To calculate this, write the number as a power of ten, and use the fact that when you raise a power to a power, you simply multiply the exponents. (10^10)100 = 10^20

To find the answer to this question, you would need to multiply ten by itself 100,000 times, which would be an immense number.
The number of 0s in the product is equal to the sum of the number of 0s in the whole number that you started with and the power [of ten].
One to one
The place value increases to the next power of 10. A Unit becomes a Ten A Ten becomes a Hundred A Hundred becomes a Thousand and so on.
You add one more zero to the end of the number
Move the decimal point to the right one time.
Move the decimal point left to multiply by a negative power of ten. For example, 5X10-3 is 0.005
To find ten percent of a number, multiply the number by 1/10, or .1 You can also divide it by ten.
When you multiply by ten to a power, move the decimal point to the right by the number of places of the power. 3.6 x 10 ^4 move decimal 4 places to right = 36000
To calculate this, write the number as a power of ten, and use the fact that when you raise a power to a power, you simply multiply the exponents. (10^10)100 = 10^20
Multiplying a real number by a positive power of ten moves the decimal point that number (the exponent) of places to the right. Multiplying by a negative power of ten moves it to the left. For example, the -3 power of 10 is 1/1000; multiplying by that moves the decimal point 3 places to the left.
Multiplication.
ok, if you multiply ten by one you get ten. If you multiply ten by two you get twenty. If you multiply ten by three you get thirty. If you multiply ten by four you get forty. Sensing a trend here yet? All those things are multiples of ten. Basically, if a number ends in a zero, it's a multiple of ten.
