The question depends on whether you mean the base is a fraction or the power. It is not clear from the question and the answer will depend on which it is.

∙ 7y agoThe laws of exponents work the same with rational exponents, the difference being they use fractions not integers.

Uranus's gravity is far stronger than earths.
This is effectively the same as lining up the decimal points when adding or subtracting ordinary decimal fractions.
you do not do anything when you add numbers with exponents. you just figure out the answer. it is only if you multiply numbers with exponents, where you add the exponents..

When multiplying two values of the same base raised to different exponents, all you need to do is add the exponents. Similarly, when dividing them, you can simply subtract the exponents. In the case of roots, the exponents are actually fractions, so you get: x1/2 ÷ x1/3 = x(1/2 - 1/3) = x(3/6 - 2/6) = x1/6

You cannot ad or subtract variables with different exponents: the exponents must be the same. The coefficients are added or subtracted and the exponent of the answer is the common exponent. (The rules are similar to those for the denominators of fractions.)Thus 2x^2 + 5x^3 cannot be combined into a single term.while 2x^2 + 5x^2 = (2+5)*x^2 = 7x^2
The exponents are added.
Rational exponents are exponents that are fractions or decimals. They are related to integer exponents because they represent a different way of expressing the same mathematical operation. For example, an integer exponent of 2 represents squaring a number, while a rational exponent of 1/2 represents taking the square root of a number.
When you multiply fractions together, you multiply the numerators together to get the numerator of the answer and you multiply the denominators together to get the denominator of the answer. For example: 1/2 * 2/3 = (1*2)/(2*3) = 2/6 = 1/3. When multiplying exponents of the same base together, you simply add the two exponents and make that the exponent of the same base. For example: 22 * 23 = 25 = 32. Or for the algebra-savvy: x2 * x3 = x5.
An integer exponent is a count of the number of times a particular number (the base) must be multiplied together. For example, for the base x, x^a means x*x*x*...*x where there are a lots of x in the multiplication. The definition is simple to understand for integer values of the exponent. This definition gives rise to the laws of exponents, and these allow this definition to be extended to the case where the exponents are negative, fractions, irrational and even complex numbers.
