A=33=27
\(B=\dfrac{2^{11}.9^2}{3^5.2^8}=\dfrac{2^{11}.3^4}{3^5.2^8}=\dfrac{2^3}{3}=\dfrac{8}{3}\)
A=3^18:3^15=3^3
B=(2^11.3^4)/(3^5.2^8)
=2^3/3=8/3
Chúc bạn học tốt!
\(A=3^{18}:3^{15}=3^3=27\)
\(B=\dfrac{2^{11}\cdot9^2}{3^5\cdot2^8}=2^3\cdot\dfrac{3^4}{3^5}=\dfrac{8}{3}\)
1. A = 318 : 315
A = 318 - 15
A = 33
A = 27
2. B = \(\dfrac{2^{11}.9^2}{3^5.2^8}\)
B = \(\dfrac{2^{11}.3^4}{3^5.2^8}\)
B = \(\dfrac{2^3.1}{3.1}\)
B = \(\dfrac{8}{3}\)
