\(10^{26}\) và \(9^{10}\)
Có: \(10>9\)
\(26>10\)
\(\Rightarrow10^{26}>9^{10}\)
C2: \(10^{26}=10^{10}.10^{16}\)
Vì: \(10^{10}>9^{10}\)
\(\Rightarrow10^{10}.10^{16}>9^{10}\)
\(\Rightarrow10^{26}>9^{10}\)
C1 10 ^ 26 = 100 ^ 25 = (100^5)^5 = 10000000000 ^ 5 > 81 ^ 5 = 9 ^10 => 10 ^ 26 > 9 ^ 10
C2 10 ^ 26 > 10^10 > 9^ 10 => 10 ^ 26 > 9 ^ 10

Ax1000 = 1830.11/5 - 672.22 -110.11/5 +1000
=(1830.11 -672.22.5-110.11+5000)/5
=(1830.11-6720.11-110.11+5000)/5=(1830.11-6830.11+5000)/5=(-5000.11+5000 )/5=-5000.10/5=-1000.10
vậy A = -10

= \(\frac{183}{100}\). \(\frac{11}{5}\)+ \(\frac{-168}{25}\). \(\frac{11}{5}\)- \(\frac{11}{100}\). \(\frac{11}{5}\)- ( - 1 )
=\(\frac{11}{5}\). ( \(\frac{183}{100}\)+ \(\frac{-168}{25}\)-\(\frac{11}{100}\)) + 1
=\(\frac{11}{5}\). ( - 5 ) +1
= - 11 + 1
= - 10
Ax1000=1830.11/5-672.22-110.11/5+1000
=(1830.11-672.22.5-110.11+5000)/5
=(1830.11-6720.11-110.11+5000)/5
=(1830.11-6830.11+5000)/5
=(-5000.11+5000)/5
=-5000.10/5
=1000.10
a: -2x+5=0
