\(=\dfrac{2^7\cdot3^6}{2^3\cdot2^6\cdot3^3}=\dfrac{1}{4}\cdot27=\dfrac{27}{4}\)
\(=\dfrac{2^7\cdot3^6}{2^3\cdot2^6\cdot3^3}=\dfrac{1}{4}\cdot27=\dfrac{27}{4}\)
1.Rut gọn
a)2^15.9^4/6^3.8^3
b)2^7.9^3/6^5/6^5.8^2
\(\dfrac{2^7.9^3}{6^5.8^2}\)
\(\dfrac{2^7.9^3}{6^58^2}\)=?
a) \(\dfrac{2^7.9^3}{6^5.8^2}\)
b) \(\dfrac{\left(0,6\right)^5}{\left(0,2\right)^6}\)
Tính:\(\frac{6^8.4^2-4^4.18^4}{27^3.8^4-3^0.2^{10}.8}\)
Các bạn giúp mình nha, nhanh mình tích cho!
a,3/2-5/6:(1/2)2+\(\sqrt{0,25-\sqrt{\dfrac{1}{4}}}\)
b,-4/3:2/9+13/12:-13/8
c,(-1/2)2-[-1/6:|-1+5|-\(\sqrt{64}.\left(\dfrac{1}{4}\right)^2\)
d,15^11.5^7.9^2/5^18.27^6
\(A=\dfrac{\left(-27\right)^{15}.5^3.8^4}{25^2.81^{11}.\left(-2\right)^{11}}\)
Ai giúp mik với!!! ai lm xong trc mik tick cho!!!
\(\dfrac{2^7.9^4}{4^4.3^9}\)
\(\dfrac{2^7.9^4}{4^4.3^9}\)
Tìm x,y,z biết:\(\dfrac{x-1}{2}\)=\(\dfrac{y+3}{4}\)=\(\dfrac{z-5}{6}\) và 5z-3x-4y=50.
giúp mình với mọi người.
