Find the gcf of each !

14. 36xy3, 24y2

15. 18y2, 54y2

16. 80x3, 39yx2

17. 105x, 30yx, 75x

18, 140n, 140m2, 80m2

some are actually in the picture.

12. 66xy, 30x²y ===> 6xy

14. 36xy3, 24y2 ===> 12y²

15. 18y2, 54y2 ===> 18y²

16. 80x3, 39yx2 ===> x²

17. 105x, 30yx, 75x ===> 15x

18, 140n, 140m2, 80m2 ===> 20

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
