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:
(1, 2) is a solution to this system of equations
Step-by-step explanation:
Plug in (1, 2) into each equation
17x + y = 19
17(1) + 2 = 19
17 + 2 = 19
19 = 19 ----------->YES
8x + 5y = 18
8(1) + 5(2) = 18
8 + 10 = 18
18 = 18 ------------------->YES
Answer:
(1, 2) is a solution to this system of equations
