Những câu sau mình làm sau nhé bạn!!!!!!!

a,3.52+(15.22-23.22)

= 156 + 22(15 - 23)

= 156 + 22. (-8)

= 156 - 176

= -20

b,75.34+76.75-75.10

= 75(34 + 76 - 10)

= 75. 100

= 7500

c,84:4+3 mũ 9 : 3 mũ 7 +2017 mũ 0

= 84 : 4 + 3⁹ : 3⁷ + 2017⁰

= 21 + 9 + 1

= 31

a) Ta có: \(3\cdot52+\left(15\cdot22-23\cdot22\right)\)

\(=3\cdot52+22\cdot\left(15-23\right)\)

\(=3\cdot52+22\cdot\left(-8\right)\)

\(=156-176=-20\)

b) Ta có: \(75\cdot34+76\cdot75-75\cdot10\)

\(=75\cdot\left(34+76-10\right)\)

\(=75\cdot\left(110-10\right)\)

\(=75\cdot100\)

\(=7500\)

c) Ta có: \(84:4+3^9:3^7+2017^0\)

\(=21+3^{9-7}+1\)

\(=22+3^2\)

\(=22+9=31\)

84:4+3⁹:3⁷+5
=21.4:4+3²+5
=21+9+5
=35

84 : 4 + 3⁹ : 3⁷ + 5

= 21 + 3^{9 - 7} + 5

= \(21 +3^{2} + 5\)

= \(21 +9 + 5\)

= 35

Đề bài như này hả bn: 84 : 4 + 3⁹ : 3⁷ + 5

\(=21+3^2+5=26+9=35\)

\(84:4+3^9:3^7+5=21+3^2+5=35\)

=21+9+5

=35
