What is 45000 in scientific notation

Q: How is the number 45, written in Scientific Notation? Why is 45, written as 4. Calculating scientific notation for a positive integer is simple, as it always follows this notation: a x 10 b Follow the steps below to see how 45, is written in scientific notation.

Step 1 To find a , take the number and move a decimal place to the right one position. Original Number: 45, New Number: 4. New Number: 4. Step 3 Building upon what we know above, we can now reconstruct the number into scientific notation. Is 45, a composite number? Is 45, an even number? Is 45, an odd number? Is 45, a perfect square? Is 45, a palindrome? Is 45, a Fibonacci number? How is the number 45, written in scientific notation? Note that the scientific notation calculator uses e plus or minus the exponent, instead of 10 raised to the exponent.

There are several different notations used, depending on the application. Computer languages, engineering and mathematical applications use similar but different ways to represent scientific notation. Embed Share via. Table of contents: What is Scientific Notation?

What is Scientific Notation? Scientific Notation Rules When converting a number into scientific notation, we must remember a few rules. Use the following steps: Place the decimal between the first two non-zero numbers, so we have 3. Count the number of decimal places that was moved, which in this case is 3. Determine whether the decimal point must be moved to the left or right to return to the original number. If the decimal is moved right, the exponent is negative.

If the decimal is moved left, the exponent is positive. Keep track of how many times we move the decimal point. Because our original number was greater than 10, the power of 10 is positive. Remember, we moved the decimal point 4 times, so the exponent is positive Scientific notation, or standard form, makes things easier when working with very small or very big numbers, both of which come up frequently in the fields of science and engineering.

Scientific notation also makes solving problems that use such high or low numbers more straightforward. Scientific Notation Also related to your input Alternative approach.
