To multiply together P = a*10x and Q = b*10y.
P and Q are in scientific form so 1 ≤ a < 10, 1 ≤ b < 10 and x and y are integers.
Step 1: PQ = (a*b)*10x+y where a*b is the ordinary multiplication of a and b.
If a*b < 10 then the above is the final answer.
If a*b > 10 then divide a*b by 10z so that a*b = c*10z where 1 ≤ c < 10 and z is an integer. When multiplying only two numbers, z can only be 1, but this rule can be applied when multiplying many scientific nuber together.
If this case, the final answer is c*10x+y+z

What is 123.45 written in scientific notation?
Such numbers would not need to be written in scientific notation but if need be it is: 1.2345*10^2
How do you add subtract multiply and divide numbers written in scientific notation?
To add or subtract numbers in scientific notation, ensure the exponents are the same; if not, adjust one of the numbers so they match before performing the operation. For multiplication, multiply the coefficients and add the exponents. For division, divide the coefficients and subtract the exponents. Finally, express the result in proper scientific notation, adjusting the coefficient to be between 1 and 10 if necessary.
Can every decimal be written in scientific notation?
Yes - you can always convert numbers to scientific notation - whether they're whole numbers, or decimals.
Why is 9.854 x 107.6 not a scientific notation?
Scientific notation is always written as a number (between 1 and 10) multiplied by a power of ten. For example: 107.6 in scientific notation would be 1.076 x 102 notice how the first number is between 1 and 10 and it is being multiplied by a power of ten. So the example you gave is not written in the same format and is thus not written in scientific notation. If you were to write it in scientific notation you would multiply the two numbers and then convert the answer to scientific notation and write it as: 1.0602904 x 103
How does scientific notation differ from ordinary notations?
Ordinary notation is where the numbers are laid, or written out. Scientific notation is a short handed version with numbers that indicate the amount of zeroes behind the end of the numbers.
How do you write 109.5 in scientific notation?
Such numbers usually are not written in scientific notation but just for the exercise it is:- 1.095*102
What is 0.000729512 in scientific notation written to 3 significant numbers?
0.000729512 in scientific notation written to 3 significant places is 7.30x10-4.
What are two examples of numbers written in scientific notation?
Here are the quick examples of the numbers written in scientific notation: 3.4 = 3.4 x 100 34.0 = 3.4 x 10
What is 226 in scientific notation?
Usually numbers under 1000 are not written in scientific notation however 226 would be written as 2.26 x 102.
Why this numbers are not written in scientific notation a. 41103 b. 0.310-7?
As far as it is possible to tell, neither of the two are in scientific notation.
When are numbers written in scientific notation?
When they are very large or very small.
Is scientific notation exponential notation?
Scientific notation is a way of writing numbers that are too big or too small to be conveniently written in decimal form. In normalized scientific notation all numbers are written in the form a x 10^b (a times ten raised to the power of b) where a is a nonzero single-digit integer and b is an integer.
