tính
4^6 . 4^5 + 6^9 . 120 / 8^4 . 3^12 - 6^11
Tính nhanh nếu có thể
a, 3/4 - [-5/3 - (1/12+2/9)]
b,( 46 . 95 + 69 . 120)/(84 . 312 - 611
4^6*9^5+6^9*120/8^4*3^12-6^11
`Answer:`
`(4^6 . 9^5 + 6^9 . 120)/(8^4 . 3^12 - 6^11)`
`= (2^12 . 3^10 + 2^9 . 3^9 . 2^3 . 3 . 5)/(2^12 . 3^12 - 2^11 . 3^11)`
`= (2^12 . 3^10 + 2^12 . 3^10 . 5)/(2^11 . 3^11(2 . 3 - 1))`
`= (2^12 . 3^10 (1 + 5))/(2^11 . 3^11 . 5)`
`= (2 . 6)/(3 . 5)`
`= 4/5`
4^6 . 9^5 + 6^9 .120 / 8^4 . 3^12 - 6^11

4^6 . 4^5 + 6^9 . 120 / 8^4 . 3^12 - 6^11
Tính 46.95+69.120/84.312-611
\(\frac{4^6.9^5+6^9.120}{8^4.3^{12}-6^{11}}\)
\(=\frac{2^{12}.3^{10}+2^9.3^9.2^3.3.5}{2^{12}.3^{12}-2^{11}.3^{11}}\)
\(=\frac{2^{12}.3^{10}+2^{12}.3^{10}.5}{2^{11}.3^{11}.\left(2.3-1\right)}\)
\(=\frac{2^{12}.3^{10}.\left(1+5\right)}{2^{11}.3^{11}.5}\)
\(=\frac{2.6}{3.5}=\frac{4}{5}\)
