Bài làm:
`A=2600:{5.[160-(3^2.3^3-213)]}`
`⇒A=2600:{5.[160-(3^{5}-213)]}`
`⇒A=2600:{5.[160-(243-213)]}`
`⇒A=2600:{5.[160-30]}`
`⇒A=2600:{5.130}`
`⇒A=2600:650=4`
`B=36:{336:[200-(12+8.20)]}`
`⇒B=36:{336:[200-(12+160)]}`
`⇒B=36:{336:[200-172]}`
`⇒B=36:{336:28}`
`⇒B=36:12=3`
`C={2.3^2+[144-5^2-(15-169:13)]}-99^0`
`⇒C={2.9+[144-25-(15-13)]}-1`
`⇒C={18+[119-2]}-1`
`⇒C=18+119-2-1=134`
`D={[(4^2.125-125):5^3].2-29}+1^2019`
`⇒D={[(16.125-125):125].2-29}+1`
`⇒D={[(2000-125):125].2-29}+1`
`⇒D={[1875:125].2-29}+1`
`⇒D={15.2-29}+1`
`⇒D={30-29}+1`
`⇒D=1+1=2`
