Simplify 8√27 (show work)
1 answer:
I was taught that if you must simplify a square root by doing the birthday cake method. Basically divide the radical by its lowest common factor until it can't be divided anymore. Also the lowest factor can't be 1. For 27, the lower common factor is 3.
27/3 = 9/3 = 3
Since in a common square root the index is 2, you must pair the least common factors. There is 1 pair of 3 and there is 1 remaining
is 3
.
You must multiply 3 and 8, which gives 24
The answer is 24

Answer:
Step-by-step explanation:
Standard form is basically where the degrees of the terms are in descending order.
First, let's distribute the negative sign to the terms in the second parentheses:
Now, we can just combine like terms with the terms from the first parentheses:
So, our answer is:
Answer:
There is no answer to this question.
Step-by-step explanation:
First of all the variable is not in the equation.
Second of all, y=mx+b has only variables, it can only be simplified to
