\(E=\frac{3^6.45^4-15^{13}.5^{-9}}{27^4.25^3+45^6}\)
\(E=\frac{3^6.3^8.5^4-3^{13}.5^{13}.5^{-9}}{3^{12}.5^6+3^{12}.5^6}\)
\(E=\frac{3^{14}.5^4-3^{13}.5^4}{3^{12}.5^6\left(1+1\right)}\)
\(E=\frac{3^{13}.5^4\left(3-1\right)}{3^{12}.5^6.2}\)
\(E=\frac{3}{25}\)
tính\(\frac{3^6.45^4-15^{13}.5^{-9}}{27^4.25^3+45^6}\)
\(\frac{3^6.45^4-15^{13}.5^9}{27^4.25^3+45^6}\)
Tính rồi chuyển thành lũy thừa : \(A=\frac{3^6.45^4-15^{13}.5^9}{27^4.25^3+45^4}\)
Tính biểu thức sau rồi chuyển thành lũy thừa :
a) 123 : 34 . 64
b) \(\frac{3^6.45^4-15^{13}.5^9}{27^4.25^3+45^6}\)
1,Tính : ( Hãy tính nhanh nếu có thể )
a,\(\frac{3^6.45^4-15^{13}.\left(\frac{1}{5}\right)^9}{27^4.25^3+45^6}\)
b,\(\frac{\left(\frac{2}{5}\right)^7.5^7+\left(\frac{9}{4}\right)^3:\left(\frac{3}{16}\right)^3}{2^7.5^2+512}\)
rút gọn A=
\(\frac{3^6.45^4-3^{10}.15^3}{27^4.25^3+45^6}\)
Rút gọn
