We need to find the least common multiple LCM for the two fractions and then multiply all terms by that number! When we move terms around, we do so exactly as we do when we solve equations!

The exponent equals the number of zeros plus the first digit in the number series. Scientists handle very large numbers like this one, as well as very small numbers, by converting them to standard form, which is a decimal number followed by an exponent of Writing Equations in Standard Form We know that equations can be written in slope intercept form or standard form.

In standard form, this is 3. Whatever you do to one side of the equation, you must do to the other side! If you How to write in standard form that you need more examples or more practice problems, check out the Algebra Class E-course. The answer is You simply add or subtract the strings of digits.

The value of the exponent indicates the magnitude of the number. Groups of Three Before converting a number to one containing an exponent, remember another convention, which is to split number strings into groups of three — or thousands — with commas.

Adding them, we get The first number is the same as X The answer is 2. If the numbers have different exponents, convert one of them to the exponent of the other. Equations that are written in standard form: If the number is large, you set the decimal after the first digit on the left, and you make the exponent positive.

For example, the first three digits of the number 12, are 1, 2 and 3. However, you must be able to rewrite equations in both forms.

This is true even if the first group contains only one or two digits. There is one other rule that we must abide by when writing equations in standard form.

Solution That was a pretty easy example. If the entire original number is greater than 1, count the numbers that appear to the right of this decimal. When you multiply numbers in standard form, you multiply the strings of numbers and add the exponents.

Note how as the decimal point moves, the exponent changes.

For standard form equations, just remember that the A, B, and C must be integers and A should not be negative. If the number is less than 1, count the numbers to the left of the decimal and multiply by 10 to a negative exponent of the number you counted.

Our first step is to eliminate the fractions, but this becomes a little more difficult when the fractions have different denominators! In standard form, the distance to the nearest star is a much more manageable 4.

You use the same strategy to convert either to standard form. For example, the number is usually writtenIn standard form, this is 5. The answer is 4. If the number is very small, the first three digits that appear after the string of zeros are the three you use at the beginning of the number in standard form, and the exponent is negative.

Positive and Negative Exponents Very small numbers, such as the radius of an atom, can be just as unwieldy as very large ones.

It equals the number of digits that follow the decimal. Sciencing Video Vault Examples:Standard Form Equation of Line-- What it is and how to graph it.

Explained with examples and pictures and many practice problems. Writing Equations in Standard Form. We know that equations can be written in slope intercept form or standard form. Let's quickly revisit standard form. Remember standard form is written. Note: Standard Form is not the "correct form", just a handy agreed-upon style.

You may find some other form to be more useful. You may find some other form to be more useful.

In Britain this is another name for Scientific Notation, where you write down a number this way. Numbers in standard form appear as a whole number followed by a decimal and two other numbers all multiplied by a power of ten.
