计算:(2.1^11x3^2)/(0.3^11x7^10)
计算:(2.1^11x3^2)/(0.3^11x7^10)

计算:(2.1^11x3^2)/(0.3^11x7^10)
(2.1^11x3^2)/(0.3^11x7^10)
=(2.1^11x9)/(2.1^11/7)
=9×7
=63

=(7x3^2)/7^10
=9/7^9

原式=(0.3^11 * 7^11 * 9)/(0.3^11 * 7^11 / 7)
=63

(2.1^11x3^2)/(0.3^11x7^10)
=[(0.3x7)^11x3^2]/(0.3^11x7^10)
=(0.3^11x7^11x3^2)/(0.3^11x7^10)
=7x3^2
=7x9
=63

(2.1^11x3^2)/(0.3^11x7^10)=(0.3^11*7^11*3^2)/(0.3^11*7^10)=7*9=63

63
