bài 1 : tính hợp lí
a) \( \left(-0,125\right)^3.80^4\)
b) \(\frac{81^{11}.3^{17}}{27^{10}.9^{15}}\)
bài 2 : rút gọn
a) \(A=\frac{16^3.3^{10}+120.6^9}{4^6.3^{12}+6^{11}}\)
b)\(B=\left(6^9.2^{10}+12^{10}\right):\left(2^{19}.27^3+15.4^9.9^4\right)\)
c)\(H=x+\frac{0,2-0,375+\frac{5}{11}}{-0,3+\frac{9}{16}-\frac{15}{22}}vs,x=-\frac{1}{3}\)
Tính:
a) \(\left(-0,125\right)^3.80^4\)
b) \(\frac{81^{11}.3^{17}}{27^{10}.9^{15}}\)
