a, \(1\frac{13}{15}\)x \(^{\left(0,5\right)^2}\) x 3 + (\(\frac{8}{15}\)-\(1\frac{19}{60}\) ) : 1\(\frac{23}{24}\)
b, so sánh \(2^{225}\) với \(3^{151}\)
So sánh A và B biét
A=\(\frac{19^{30}+5}{10^{31}+5}\)và B=\(\frac{19^{31}+5}{19^{32}+5}\)
A= \(\frac{2^{18}-3}{2^{20}-3}\)và B = \(\frac{2^{20}-3}{2^{22}-3}\)
A = \(\frac{1+5+5^2+.......+5^9}{1+5+5^2+.....+5^8}\) B = \(\frac{1+3+3^2+.....+3^9}{1+3+3^2+.......+3^8}\)
