A: 4-16-{-30-[40+(16-20)]}=

B: 4/3x[2/5-(1/2+6/5)]=

C: (1/2-10)÷(2/4+3/5)=

D: 4/9-(-2/5+1/2)-3/10=

E: (9/2)(-5/2)(-4)+(1/2÷6)-(3/5)(-10)(4/3)=

F: √144- 5²

Answer 1

A) 4-16-{-30-[40+(16-20)]}
4-16-{-30-[40-4]}
4-16-{-30-36}
4-16+66
4+50=54

B) 4/3x[2/5-(1/2+6/5)]
4/3x[2/5-(5/10+12/10)]
4/3x[2/5-17/10]
4/3x[4/10-17/10]
4/3x[-13/10]
-26/15

C) -5: [10/20+12/20]
-5: 22/20
-5 x 20/22= -50/11

Ya me dio pereza XD
F) 12-25= -13
