\(\frac{2^7\cdot9^3}{6^5\cdot8^2}\)
\(=\frac{2^7\cdot3^6}{3^5\cdot2^5\cdot2^6}\)
\(=\frac{3}{16}\)
\(\frac{2^7\cdot9^3}{6^5\cdot8^2}\)
\(=\frac{2^7\cdot3^6}{3^5\cdot2^5\cdot2^6}\)
\(=\frac{3}{16}\)
\(\frac{2^{15}\times9^4}{6^6\times8^3}\)
Làm hộ mình cái nha!
Tính GT biểu thức:( tính nhanh )\(C=\frac{2^{15}\times9^4}{6^6\times8^3}\)
*Tính:
\(\frac{2^5\times9^4}{6^6\times8^3}\)
\(\frac{1}{3\times4}-\frac{1}{4\times5}-\frac{1}{5\times6}-\frac{1}{6\times7}-\frac{1}{7\times8}-\frac{1}{8\times9}-\frac{1}{9\times10}\)
\(\dfrac{4^{10}\times9^6+3^{12}\times8^5}{6^{13}\times4+2^{16}\times3^{12}}\)
Rút gọn
a)\(\frac{4^2\times4^3}{2^{10}}\)
b)\(\frac{\left(0.6\right)^5}{\left(0.2\right)^6}\)
c)\(\frac{2^7\times9^3}{6^5\times8^2}\)
d)\(\frac{6^3+3\times6^2+3^3}{-13}\)
Cuối cùng: Tìm giá trị của biểu thức sau:
a)\(\frac{4^2\times4^3}{2^{10}}\)
b)\(\frac{\left(0,6\right)^5}{\left(0,2\right)^6}\)
c)\(\frac{2^7\times9^3}{6^5\times8^2}\)
d)\(\frac{6^3+3\times6^2+3^3}{-13}\)
Tính hợp lí
H = \(\frac{2\times8^4+27^2+4\times6^9}{2^7\times6^7+2^7\times40\times9^4}\)
Tính
a)\(A=\frac{\left(3\times2^{20}+7\times2^{19}\right)\times52}{\left(13\times8^4\right)^2}\)
b)\(B=\frac{2^{19}\times27^3+15\times4^9\times9^4}{6^9\times2^{10}+12^{10}}\)
