這條數怎樣計呢?

你要用對數再加上計算機先計到:
1997^2006 + 2007^2006
= 10^ (log 1997^2006) + 10^(log 2007^2006)
= 10^(2006 log 1997) + 10^(2006 log 2007)
= 10^6620.558398 + 10^6624.910029
= (10^6620)(10^0.558398) + (10^6624)(10^0.910029)
= 3.617413283 x 10^6620 + 8.12885184 x 10^6624
= 8.129213581 x 10^6624

使用的參考公式如下:1. log a^n = n log a2. a^(m n) = (a^m)(a^n)3. n = 10^(log n)希望可以幫到你

1997的2006次方 + 2007的2006次方
=1997^2006+2007^2006
=這條數要用計算機計！

i think you better use the calculator
