Ayudaaaaaaaaaaaaaaaaaaa porfaaaaaaaaaaa

Answer 1

a)2x(³\/-8+1⁷+4\/16) ÷ (-8+³\/125)×2-⁵\/32

2x(-2+1+4(4)) ÷ (-8+5)×2-2

2x(-2+1+16) ÷ (-3)×2-2

2x(15) ÷ -6-2

2x(15) ÷ 8

30 ÷ 8

3.75

b)7(³\/-27+2²+3\/9) + (-12+³\/512)×5-9

7(-3+4+3(3)) + (-12+8)×5-9

7(-3+4+9) + (-4)×5-9

7(10) + -20-9

70 + -29

70 - 29

41

c)³\/-125+4-2³÷(4-2)+9-(16×\/4)-7

-5+4-8 ÷ 2+9-(16×2)-7

-5+4-8 ÷ 2+9-(32)-7

-5+4-8 ÷ 2+9-32-7

-1-8 ÷ 11-32-7

-9 ÷ -21-32-7

-9 ÷ -53-7

-9 ÷ -60
