\(M=\frac{3^6.3^8.5^4-3^{15}.5^{13-9}}{3^{12}.5^6+3^{18}.5^9}.2.\frac{25}{9}=\frac{3^{14}.5^4\left(1-3\right).2.5^2}{3^{12}.5^6\left(1+3^6.5^3\right).3^2}=\frac{-4}{1+3^6.5^3}\)
Tính:\(\frac{3^6.45^4.-15^{13}.5^{-9}}{27^4.25^3+45^6}\)
1) Tinh :a) \(\frac{3^6.45^4-15^{13}.5^{-9}}{27^4.25^3+45^6}-\frac{50}{7}.\frac{\sqrt{0,49}}{25}\)
b) Tim x , biet: \(|2x-\frac{1}{5}|\left(-\frac{1}{5}\right)^5=\left(-\frac{1}{5}\right)^7\)
\(\frac{3^6.45^4-15^{13}.5^{-9}}{27^4.25^3+45^6}=?\)
tính nhanh
\(\frac{3^6.45^4-15^{13}:5^9}{27^4.25^3+45^6}\)
\(\frac{3^6.45^4-15^{13}.5^{-9}}{27^4.25^3+45^6}\)=?
2) rút gọn
\(A=\frac{3^6.45^4-15^{13}.5^{-9}}{27^4.25^3+45^6}\)
Tính
\(\frac{3^6.45^4-15^{13}.5^9}{27^4.25^3+45^4}\)
Tính
\(\frac{3^6.45^4-15^{13}.5^9}{27^4.25^3+45^6}\)
Tính:
\(\frac{3^6.45^4-15^{13}.5^{-9}}{27^4.25^3+45^6}\)
Làm ơn giúp mn nha~
