更新1:
is it
-2K^12 OR
-2K^-12
回答 (8)
✔ 最佳答案
- 2
----------
(k^7)(k^5)
- 2
-------
k^12
1/(-16K^7)(8K^5)
1/(-128K^12)
(-16K^-7)/(8K^5) =
(-16/8)(K^-7.K^-5)=
-2 K^-12
hi,
factor numerator and denominator.
and remember that:
a^m/a^n = a^(m-n)
therefore:
(-16K^-7) / (8K^5)
=[(8)(-2)/8] K^-7-5 --> common factor is 8.
= (-2)K^-12 --> note: a^-n = 1/aⁿ
= (-2)(1/K^12)
= -2/K^12. --> answer.
.........
simplified form of (-16K^-7) / (8K^5) is -2/K^12.
hope it helps.
(-16k^-7)/(8k^5)
= (-16/k^7)/(8k^5)
= -16/k^7 x 1/8k^5
= -16/8k^12
= -2/k^12
(-16K^-7)/(8K^5)= - 2K-7/K^5= -2K^-12
