tính giúp mik nhé
Rút gọn phân số
7.4^5.3^11+2^13.9^5/6^10+2^12.3^10
So sánh :
A = \(\frac{1+2+3+4+5+6}{7+8+9+10+11+12}\) ; B = \(\frac{1+2+3+4+5+6+7}{7+8+9+10+11+12+13}\)
Tính nhanh:
a/\(\left(2+\frac{-7}{13}\right)+\frac{-6}{13}\)
b/\(\frac{-5}{11}+\left(\frac{2}{3}+\frac{-6}{11}\right)\)
c/\(\frac{5}{9}+\frac{-7}{11}+\frac{9}{29}+\frac{4}{9}+\frac{-4}{11}\)
( tự suy nghĩ đề )
\(M=\frac{9^4.27^5.3^6.3^4}{3^8.81^4.234.8^2}\)
\(N=\frac{4^6.9^5+6^9.120}{8^4.3^{12}-6^{11}}\)
