\(=\frac{3^6.9^4.5^4-3^{13}.5^{13}.5^9}{3^{12}.5^6+9^4.5^4}=\frac{3^6.3^8.5^4-3^{12}.5^{22}}{3^{12}.5^6+3^8.5^4}=\frac{5^4.3^{12}\left(3^{12}-5^{18}\right)}{5^4.3^8\left(3^4.5+1\right)}=\frac{3^4.\left(3^{12}-5^{18}\right)}{3^4.5+1}\)
\(=\frac{3^6.9^4.5^4-3^{13}.5^{13}.5^9}{3^{12}.5^6+9^4.5^4}=\frac{3^6.3^8.5^4-3^{12}.5^{22}}{3^{12}.5^6+3^8.5^4}=\frac{5^4.3^{12}\left(3^{12}-5^{18}\right)}{5^4.3^8\left(3^4.5+1\right)}=\frac{3^4.\left(3^{12}-5^{18}\right)}{3^4.5+1}\)
Tính biểu thức sau rồi chuyển thành lũy thừa :
a) 123 : 34 . 64
b) \(\frac{3^6.45^4-15^{13}.5^9}{27^4.25^3+45^6}\)
tính:
\(E=\frac{3^6.45^4-15^{13}.5^{-9}}{27^4.25^3+45^6}\)
tính\(\frac{3^6.45^4-15^{13}.5^{-9}}{27^4.25^3+45^6}\)

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=
\(\frac{3^6.45^4-3^{10}.15^3}{27^4.25^3+45^6}\)
Viết kq phép tính sao dưới dạng lũy thừa :
a,4 mũ 13 nhân 5 mũ 13
b, 27 mũ 16 chia 9 mũ 10
c,16 mũ 3 : 8 mũ 4
Tính rồi chuyển thành lũy thừa :
A = 123 : 34 .64
Rút gọn
d= 2^10.13+2^10.65 / 2^8.65
E=3^6.45^4-15^3:5^9 / 27^4+45^6
