a; \(x\) - 2 = 24

\(x\) = 24 + 2

\(x\) = 26

Vậy \(x\) = 26

b; 5.(5 - \(x\) ) = -25

25 - 5\(x\) = - 25

5\(x\) = 25 + 25

5\(x\) = 50

\(x\) = 50 : 5

\(x\) = 10

Vậy \(x\) = 10

c; 3\(x\) - 7 = 22.5

3\(x\) = 22.5 + 7

3\(x\) = 110 + 7

3\(x\) = 117

\(x\) = 117 : 3

\(x\) = 39

Vậy \(x\) = 39

\(\frac{2^{11}.9^3}{3^5.16^2}\)

= \(\frac{2^{11}.3^6}{3^5.2^8}\)

= \(\frac{2^{11}}{2^8}\frac{.3^6}{3^5}\)

= \(2^{11-5}.3^{6-5}\)

= \(2^3.3\)

= 8.3

= 24
