Webb21 dec. 2024 · When it comes to factoring negative fractional exponents, you can combine what you've learned about factoring expressions with negative exponents and those with fractional exponents. Remember, x^ {-y} = \frac {1} {x^y} x−y = xy1. regardless of what's in the y spot; y could even be a fraction. So if you have an expression x − a / b , that's ... Webb8 dec. 2024 · Tackle divisions of two numbers with fractional exponents by subtracting the exponent you’re dividing (the divisor) by the one you’re dividing (the dividend). For example: x^ {1/2} ÷ x^ {1/2} = x^ { (1/2 - 1/2)} \\ = x^0 = 1 x1/2 ÷x1/2 = x(1/2−1/2) = x0 = 1. This makes sense, because any number divided by itself equals one, and this ...
WebbAn index can also be a fraction such as ½, ¾, or 2.5. Read this section to see what this means, and how the laws of indices apply to fractional indices. In another module, the index laws were introduced and example were given of their application. The actual indices were whole numbers. But the index laws also work with fractional indices.
