Simplify 72x6 y7 z .
Solution:
[tex] 72*x^{6}*y^{7}*z^{1} [/tex]
There is nothing we can simplify more. If we had
[tex] 12*x^{6}*x^{7}*6*x^{1} [/tex]
=[tex] 12*6*x^{6+7+1} [/tex]
=[tex] 72*x^{14} [/tex]
But, there are no terms that have same base so we can not simplify the exponents, neither we have constant terms in product. So, we can not simplify this.
If we expand
[tex] 72*x^{6}*y^{7}*z^{1} [/tex]
we get,
=[tex] 2*2*2*3*3*x*x*x*x*x*x*y*y*y*y*y*y*y*z [/tex]
So, [tex] 72*x^{6}*y^{7}*z^{1} [/tex]=[tex] 2*2*2*3*3*x*x*x*x*x*x*y*y*y*y*y*y*y*z [/tex]
