Có:2437=(35)7=335
910x275=(32)10x(33)10=320x330=350
=>..
Ta có:910 = (32)10 =320
275 = (33)5 =315
2437 =(35)7=335
910+275=320+315=335
Mà 335=335
Vậy 2437=910+275
243^7 9^10 x 27^5
= (3^5)^7 = (3^2)^10 x (3^3)^5
= 3^35 = 3^20 x 3^15
= 3^35
Vi 3^35 = 3^35
=> 243^7 = 9^10 x 27^5
Vay 243^7 = 9^10 x 27^5
