\(\frac{4^6.9^5+6^9.120}{-6^{11}-8^4.3^{12}}\)
Tính :
\(A=\frac{4^6.9^5+6^9.120}{-8^4.3^{12}-6^{11}}\)
1. thực hiện phép tính
a. A=[\(6.\left(\dfrac{-1}{3}\right)-3.\left(\dfrac{1}{3}\right)+1\)]:\(\left(-\dfrac{1}{3}-1\right)\)
b. B=\(\dfrac{4^6.9^5+6^9.120}{8^4.3^{12}-6^{11}}\)
Tính giá trị của biểu thức :
B = \(\dfrac{4^6.9^5+6^9.120}{-8^4\cdot3^{12}+6^{11}}\)
Tính giá trị các biểu thức sau:
a, A = \(\left(3\dfrac{5}{6}-1\dfrac{1}{3}\right)\left(3\dfrac{4}{15}-2\dfrac{3}{5}\right)\)
b, B= \(\dfrac{4^6.9^5+6^9.120}{8^4.3^{12}-6^{11}}\) c, C = \(\left(1-\dfrac{1}{3}\right)\left(1-\dfrac{1}{6}\right)\left(1-\dfrac{1}{10}\right)\left(1-\dfrac{1}{15}\right)...\left(1-\dfrac{1}{210}\right)\)
