Lutasin ang 7u^{9}v^3w^6-21u^2v^4

$$7 u ^ { 9 } v ^ { 3 } w ^ { 6 } - 21 u ^ { 2 } v ^ { 4 }$$

I-factor

$$7u^{2}v^{3}\left(w^{6}u^{7}-3v\right)$$

Mga Hakbang ng Solution

I-factor out ang 7.

$$7\left(u^{9}v^{3}w^{6}-3u^{2}v^{4}\right)$$

Isaalang-alang ang u^{9}v^{3}w^{6}-3u^{2}v^{4}. I-factor out ang u^{2}v^{3}.

$$u^{2}v^{3}\left(u^{7}w^{6}-3v\right)$$

I-rewrite ang kumpletong naka-factor na expression.

$$7u^{2}v^{3}\left(u^{7}w^{6}-3v\right)$$

I-evaluate

$$7u^{2}v^{3}\left(w^{6}u^{7}-3v\right)$$
