Tặng người giải mỗi ngày ba điểm hđ :)
Tính hợp lí :
a,\(\left(20.2^4-12.2^3-48.2^2\right)^2:\left(-8\right)^3\)
b,\(\frac{5.4^{15}-9^9-4.3^{20}.8^9}{5.2^9.6^{19}-7.2^9.27}\)
Giúp mik mik sẽ cho 3 tick ,Thanks !
A = \(\frac{5.4^{15}.9^9-4.3^{20}.8^9}{5.2^9.6^{19}-7.2^{29}.27^6}\)
B = 3.{ 5 . [ ( 5^2 + 2^3 ) : 11 ] -16} + 2015
C = \(\left(1+\frac{1}{1.3}\right).\left(1+\frac{1}{2.4}\right).\left(1+\frac{1}{3.5}\right).....\left(1+\frac{1}{2014.2016}\right)\)
1)tính
\(\frac{5.4^{15}.9^9-4.3^{20}.8^9}{5.2^9.6^{19}-7.2^{29}.27^6}\)
2) tìm x biết
a)\(1\frac{1}{30}:24\frac{1}{6}-24\frac{1}{5}-\frac{1\frac{1}{2}-\frac{3}{4}}{4x-\frac{1}{2}}=\left(-1\frac{1}{15}\right):\left(8\frac{1}{5}-8\frac{1}{3}\right)\)
đúng mình tick
Tính:
\(\frac{5.4^{15}.9^9+4.3^{20}.\left(-8^9\right)}{5.2^9.6^{19}-7.2^{29}.27^6}\)
Thực hiện phép tính:
\(\frac{5.4^{15}.\left(-9\right)^9-4.3^{20}.8^9}{5.2^9.6^{19}-7.2^{29}.27^6}\)
Bài 1. Tính
\(A=\frac{2181.729+243.81.27}{9.81.324+18.54.162.9+723.729}\)
