Answer 1

Verified answer

180:5×6(1-5) =
36×6(-4) =
216(-4) = -864

a)
3/6+4/7-1/6 =
3/6-1/6+4/7 =
2/6+4/7 =
1/3+4/7 =
7/21+12/21 = 19/21

b)
(3/4)² - (2/3)² - (1/4)² =
9/16 - 4/9 - 1/16 =
9/16 - 1/16 - 4/9 =
8/16 - 4/9 =
1/2 - 4/9 =
9/18 - 8/18 = 1/18


p = 4
g = 3
r = -2

a)
p² - gr =
4² - (3)(-2) =
16 - (-6) =
16 + 6 = 22

b)
2p² - 2g² =
2(4²) - 2(3²) =
2(16) - 2(9) =
32 - 18 = 14
