whats the excluded value of 30k - 20 over 90k
What value of k will make the expression
(30k-20)/90k
undefined?
Look carefully at the denominator.
To find the excluded value in the expression 30k - 20 over 90k, we need to identify which value(s) of k would make the denominator equal to zero.
In this case, the denominator is 90k. To find the excluded value(s), we set the denominator equal to zero and solve for k:
90k = 0
Dividing both sides of the equation by 90, we get:
k = 0
Therefore, the excluded value in the expression 30k - 20 over 90k is k = 0.
