\(328-\left[x-\left(33.32-29:22\right).2\right]=274\)

\(328-\left[x-\left(1056-\frac{29}{22}\right).2\right]=274\)

\(x-2112+\frac{29}{11}=328-274\)

\(x-2112+\frac{29}{11}=54\)

\(x=54+2112-\frac{29}{11}\)

\(x=\frac{23797}{11}\)

vậy \(x=\frac{23797}{11}\)

a)  13 15 : 39 25 = 13 15 . 25 39 = 5 9

b)  2 9 : 27 4 = 2 9 . 4 27 = 8 243

c)  − 7 8 : ( − 3 ) = − 7 8 . − 1 3 = 7 24

\(2.3^x=10.3^{12}+8.27^4\)

\(2.3^x=10.3^{12}+8.\left(3^3\right)^4\)

\(2.3^x=18.3^{12}\)

\(3^x=9.3^{12}=3^{14}\)

\(x=14\)

2.3ˣ = 10.3¹² + 8.27⁴

2.3ˣ = 10.3¹² + 8.(3³)⁴

2.3ˣ = 10.3¹² + 8.3¹²

2.3ˣ = 3¹².(10 + 8)

2.3ˣ = 3¹².18

3ˣ = 3¹².18 : 2

3ˣ = 3¹² . 9

3ˣ = 3¹² . 3²

3ˣ = 3¹⁴

x = 14

15¹² = 3¹².5¹²

27⁴.25⁶ = (3³)⁴.(5²)⁶ 

27⁴ = 3¹².5¹² 

15¹² = 27⁴.25⁶

27⁴.5⁶ = (3³)⁴.(5²)⁶ = 3¹².5¹² = 15¹²

Vậy 15¹² = 27⁴.5⁶

327/929 lớn hơn

so sánh 274/871 và 327/929

ta có: +] 1-274/871=597/871

          +]1-327/929=602/929

\(\Rightarrow\)597/871>602/929

vậy 274/871>327/929
