Fractional Exponents - Math is Fun
WebAug 31, 2024 · Usually you see exponents as whole numbers, and sometimes you see them as fractions. Rarely do you see them as decimals. When you do see an exponent that is a decimal, you need to convert the decimal to a fraction. Then, there are a number of rules and laws regarding exponents you can use to calculate the expression. WebSo for division with the same base, you subtract the exponent. If you have 3^3 / 3^3, you would have 3^ (3-3) = 3^0 because of this rule, so 3^0 = 3^3/3^3, which turns out to be 1. Anything to the 0th power is 1. if you take 3^0 / 3^1, you have 3^-1, which is also 1/3, so it's the reciprocal. I hope this makes sense to you. 2 comments ( 9 votes) high rack vehicles texas
