Answer:
Rational exponents are not defined when the denominator of the exponent in lowest terms is even and the base is negative.
Step-by-step explanation:
Considering the expression
![X^{\frac{a}{b}}=\sqrt[b]{X^a};\:\:\:\:\:\:\:\:\:b\ne 0](https://tex.z-dn.net/?f=X%5E%7B%5Cfrac%7Ba%7D%7Bb%7D%7D%3D%5Csqrt%5Bb%5D%7BX%5Ea%7D%3B%5C%3A%5C%3A%5C%3A%5C%3A%5C%3A%5C%3A%5C%3A%5C%3A%5C%3Ab%5Cne%200)
Here:
A rational exponent - an exponent that is a fraction - is the kind of way we may write a root.
If the denominator is an even number, it means we are talking about an even root like square root, 4th root, 6th root etc.
For example, think about squaring a number
-4 × -4 = 16, 4 × 4 = 16
It means any number when it get multiplied by itself an even number of times, it would always yield a positive number.
It is not possible to take the square root of a negative number as we can not yield a negative number when we square the number. In other words, there is no way we can multiply the same negative number twice and get a negative number. This is why
is undefined.
Therefore, rational exponents are not defined when the denominator of the exponent in lowest terms is even and the base is negative.
Simply find common multiple. x=72
Answer:
A and B only
Step-by-step explanation:
The table has x=10 that maps on to y=5 and y=-5.
This disqualifies the table for being a function.
The ordered pairs has no x-value repeating.
The graph of y=x² +10 is a vertical parabola that passes the vertical line test, hence it is also a function.
For a relation to be a function, no x-value must repeat; this means its graph must pass the vertical line test
3 Times 6 + 9 would be how to do it first multipy 3 time 6 and the add your 9 to to answer off 3 times 6 so the answer would be 3 times 6 + 9= 27
