# How to write answer in scientific notation

Oops - the answer really is 4. We just continue to move the decimal point a certain number of spaces to the right depending on the power of 10 that we are multiplying.

Your resulting calculation will be rounded from 4. If you have a negative power of 10, you must move the decimal point to the left! There is a specific format in which you must write a number in order for it to be considered scientific notation.

Your answer should be 2. We are creating a smaller number! Very small numbers are converted to an equivalent decimal number between 1 and 10, multiplied by 10 raised to some negative power. Write in scientific notation: Remember that taking the square root is the same as raising the number to the one-half power.

Using the property of quotients of powers, we have Note that for any a not equal to zero, the left-hand member equals 1 and the right-hand member equals a0. Note that the inputs are standard notation numbers.

If you studied the lesson on negative exponentsthen you learned that when you raise a whole number to a negative power, it results in a fraction because you take the recipocal. Are you ready to look at a few problems where the power of 10 is negative?

The digit terms are multiplied in the normal way and the exponents are added. In E notation the "times 10 raised to a power" is replaced with the letter e in either uppercase or lowercase.

Divide b into be to obtain the building factor c. Write in Expanded Form Example 2: The quotient is changed if necessary so that there is only one nonzero digit to the left of the decimal.

See the Scientific Notation Converter to convert a number into scientific notation or E notation.Scientific notation is the expression of a number based on the largest exponent of 10 for its value, where the form is a decimal number A x 10n.
