\(5^{108}:5^{106}+2022^0-2^3:8=5^2+1-8:8=25+1-1=25\)

= 25

5¹⁰⁸ : 5¹⁰⁶ + 2022⁰ - 2³ : 8
= 5² + 1 - 8 : 8 
= 25 + 1 - 1
= 25

 

\(2040-\left[10\left(4^3-56\right):2^3+2^3\right].2022^0\)

\(=2040-\left[10.8:2^3+2^3\right].1\)

\(=2040-\left(10+2^3\right)\)

\(=2040-18=2022\)

a: \(\left(-150\right):\left(-5\right)-2\cdot5^2\)

\(=\dfrac{150}{5}-2\cdot25\)

=30-50

=-20

b: \(2040-\left[10\cdot\left(4^3-46\right):18+2^3\right]\cdot2022^0\)

\(=2040-\left[10\cdot\left(64-46\right):18+8\right]\)

\(=2040-\left[10\cdot18:18+8\right]\)

\(=2040-10-8=2030-8=2022\)

Bài 1

a) 15 + 4.12 - 3²

=15 + 48 - 9

= 63 - 9

= 54

b) {[(37 + 13) : 5].2 - 45 : 5}.7 - 2022⁰

= [(50 : 5).2 - 9].7 - 1

= (10.2 - 9).7 - 1

= (20 - 9).7 - 1

= 11.7 - 1

= 77 - 1

= 76

Bài 2

a) 13x + 3 = 16

13x = 16 - 3

13x = 13

x = 13 : 13

x = 1

b) 2x - 138 = 2⁴ : 2³

2x = 2 + 138

2x = 140

x = 140 : 2

x = 70

\(5108+471-108-236-414+529\)

\(=\left(5108-108\right)+\left(471+529\right)-\left(236+414\right)\)

\(=5000+1000-650\)

\(=6000-650\)

\(=5350\)

5350 nhé bn

5108 + 471 - 108 - 236 - 414 + 529

= ( 5108 - 108 ) + ( 471 + 529 ) - ( 236 + 414 )

= 5000 + 1000 - 650

= 6000 - 650

= 5350
