GIÚP MÌNH VỚI MÌNH ĐANG CẦN GẤP:v
1) so sánh
P=131.145+100 và Q= 45^5.5-7^11
45+132.145 (-7)^10.5-249^5
2) Rút gọn
a) M=4^6 .9^5+6^9.120 b) N= 2^16.9^2 c)P= 11^4.6-11^3 : 9^8.3-9^9 : 10^5-10^5.3
8^4.3^12-6^11 6^5.8^3 11^4-11^5 9^8.5+9^8.7 10^5.11

\(M=\frac{131.145+100}{45-132.145}\)
\(=\frac{131-\frac{100}{145}}{\frac{45}{145}-132}\)
\(=\frac{131-\frac{20}{29}}{\frac{9}{29}-132}\)
\(=\frac{131\frac{-20}{29}}{-132\frac{9}{29}}\)
\(\frac{131.145+100}{45-132.140}=\frac{132.145-45}{45-132.140}=-1\)
\(\frac{49^6.5-7^{11}}{\left(-7\right)^{10}.5+2.49^5}=\frac{7^{11}.7-7^{11}.1}{7^{10}.5+2.7^{10}}=\frac{7^{11}.\left(7-1\right)}{7^{10}.\left(5+2\right)}=\frac{7^{11}.6}{7^{11}}=6\)
\(\frac{131.145+100}{45-132.145}=\frac{131.145+100}{45-145-131.145}=\frac{131.145+100}{-100-131.145}=\frac{131.145+100}{-\left(131.145+100\right)}=-1\)
a. \(\frac{20^5.5^{10}}{100^5}\)= \(\frac{20^5.5^{10}}{20^5.5^5}\)= \(5^5\)=\(3125\)
b. \(\frac{0,9^5}{0,3^6}\)= \(\frac{0,9^5}{0,3^5.0,3}\)= \(\left(\frac{0,9}{0,3}\right).\frac{1}{0,3}\)= \(243.\frac{1}{0,3}\)= \(810\)
c.\(\frac{6^3+3.6^2+3^3}{-13}=\frac{\left(3.2\right)^3+3.\left(3.2\right)^{^2}+3^3}{-13}=\frac{3^3.2^3+3.3^2.2^2+3^3}{-13}\)\(=\frac{3^3\left(2^3+2^2+1\right)}{-13}=\frac{3^3.13}{-13}=3^3.\left(-1\right)=-27\)
a. \(\dfrac{656565}{272727}=\dfrac{65}{27}\)
b. \(\dfrac{2}{7}\left(\dfrac{3}{4}+\dfrac{9}{4}\right)=\dfrac{6}{7}\)
