Yes, but ONLY if the base is 10 .

How do you put things out of scientific notation?
If the exponent is positive, move the decimal to the right the same number of spaces as the number of the exponent. If the exponent is negative, move the decimal to the left the same number of spaces as the number of the exponent.Examples:2.5 x 103 is 2500 in standard notation. (Move the decimal to the right 3 spaces.)4.9 x 10-5 is 0.000049 in standard notation. (Move the decimal to the left 5 spaces.)
HOW DO convert scientific notation to decimalnumbers?
The exponent tells you how many spaces to move the decimal, remember to add zeros as needed. If the exponent is negative make it a decimal number less than one by moving the decimal to the left. If the exponent is positive make the decimal number greater than one by moving the decimal to the right.
What is the significance of the exponent to which 10 is raised when using scientific notation?
The exponent indicates how many spaces to move the decimal point to the right (+) or to the left (-) when expanded.
What are the rules of changing number to Scientific notation?
Move the decimal until there is one nonzero digit to the left of the decimal counting the spaces that you move the decimal. That number of spaces becomes the exponent of 10. The exponent is positive if the original number was greater than 10, but is negative if the original number is less than one.
What is the rule for dividing by 0.01?
Move the decimal point in the numerator two places to the right. If necessary, add up to two 0s.For example,2/0.01 = 2002.3/0.01 = 2302.34/0.01 = 2342.345/0.01 = 234.5

What is it called when you move a decimal point to the right?
When you move a decimal point to the right you are multiplying a number by 10. For example, take 3.4. If you move the decimal point to the right you get 34. This is the same as: 3.4x10 = 34. Reversing this, you are dividing by 10 by moving the decimal point to the left. For example, take 73. If you move the decimal point to the right you get 7.3. This is the same as: 73/10 = 7.3. If you move a decimal point 2 spaces to the right, you are multiplying by 100, or more generally if you move the decimal point n spaces to the right, you are multiplying by 10^n.
How do you convert scientific notation to decimal notation?
If the number in sci. notation has a positive exponent, move the decimal to the right the same number of spaces as the exponent's number. For example: 5.78 x 103 = 5780 If the exponent is negative, move the decimal to the left the same number of spaces as the exponent's number. For example: 2.945 x 10-5 = 0.00002945

What is an algorithm for dividing decimals and tell why the algorithm works?
Decimals are the equivalent of fractions. get rid of the decimal in the divisor by moving it to the right end of the number, count spaces moved and move the decimal in the dividend the same number of spaces (adding zeros if necessary). This works because to get an equivalent fraction you multiply the numerator (dividend) and the denominator (divisor) by the same number. Moving a decimal to the right is the same as multiplying by 10, 100, 1000, etc. if you move the decimal 1, 2, 3, etc. spaces so you are in effect multiplying both by these multiples of 10 by moving the decimal the same number of spaces. After this just follow the rules for division, divide an appropriate number of spaces, multiply, subtract, bring down, etc.

When dividing two whole numbers to get a percent how many spaces do you move the decimal?
one space right
How do you put a number into scientific notation?
To put a number into scientific notation, first identify the decimal point's position to get a number between 1 and 10. Then, write this number followed by the multiplication sign "×" and 10 raised to the power of the decimal places the decimal point moved. If the decimal point moves to the left, the exponent is positive, and if it moves to the right, the exponent is negative.
Which way do you move the decimal when dividing?
You always move the decimal to the right when dividing by a number which is not a whole number. For example: In the problem 100 divided by .01, you would move the decimal two places to the right for divisor and dividend leaving you with 10000 divided by 1.
What is 100 times 1000?
100,000 If you are multiplying or dividing by any number that starts with 1 and ends with a 0, you simply move the decimal. For example: for 100 times 1000 you move 100's decimal three spaces to the right, because there are three 0's in 1000. If you want to divide, you move the decimal to the left. NOTE: There is an imaginary decimal at the end of every number. For example: (where the period is, that is where the decimal should be) 100.
