Can negative numbers have fractional exponents?
A negative fractional exponent works just like an ordinary negative exponent. First, we switch the numerator and the denominator of the base number, and then we apply the positive exponent. Examples: 49 = 73 = 343.
What is 3 to the power of negative 2 as a fraction?
1/9
3 to the power of negative 2 is 1/9.
What happens when an exponent is a fraction?
When the exponent is a fraction, you’re looking for a root of the base. The root corresponds to the denominator of the fraction. For example, take “125 raised to the 1/3 power,” or 125^1/3. The denominator of the fraction is 3, so you’re looking for the 3rd root (or cube root) of 125.
Can you leave a negative exponent in the denominator?
In other words, negative exponents in the numerator can be written as positive exponents in the denominator, and negative exponents in the denominator can be written as positive exponents in the numerator. Example 7: Simplify: − 2 x − 5 y 3 z − 2 .
How do I make a fraction into a negative exponent?
Multiplication Law (same bases): xaxb = xa+b
Why does a negative exponent equal a fraction?
– Here we have an expression involving power of ten with a negative exponent. The base is 10 and the exponent is −3. – In normal course the value of 10 -3 can be found by multiplying the base 10 three times in the denominator and putting a 1 in the numerator. – Using a shortcut, we find that the exponent is -3.
How do you calculate negative exponents?
