Question

Câu 1: Thực hiện phép tính

a/96:2^4 +3^2-2018^0

b/32.77+32.24-32

c/{2.3^2+[144-5^2.(15-169:13)]}-1^2019

d/5^27.5:5^25+|-125|

Answer 1

a) \(96 : 2^4 + 3^2 - 2018^0 \)

= 96 : 16 + 9 - 1

= 6 + 9 - 1

= 15 - 1

= 14

b) 32 . 77 + 33 . 24 - 32

= 2541 + 768 - 32

= 3309 - 32

= 3327

c) \({2 . 3^2 + [144 - 5^2 . (15 - 169 : 13)]} - 1^2019\)

1^2019 nha bạn

= 2 . 9 + [144 - 25 . (15 - 169 : 13)]}- 1

= 2 . 9 + [144 - 25 . (15 - 13)]}- 1

= 2 . 9 + [144 - 25 . 2]}- 1

= 2 . 9 + [144 - 50]}- 1

= 2 . 9 + 94 - 1

= 18 + 94 - 1

= 112 - 1

= 111

d) 5^27 . 5 : 5^25 + -125 = 0
