Question

Evaluate. 9!/6!3! a1 b84 c168

Answer 1

Step-by-step answer:

The question is most probably missing parentheses and should read

9! ./ (6!3!)

= 9*8*7 / (3*2*1)

=84

The question as-is should be interpreted as follows, following the normal PEDMAS rules:

(9!/6!) * 3!

= (9*8*7)*(3*2*1)

= 504 * 6

= 3040

Note that when interpreting typeset formulas, all denominators and numerators should be enclosed in parentheses to translate correctly mathematical formulas.  Most automated translators / scanners are not capable of doing that.

Answer 2

Answer:

84

Step-by-step explanation:

$\tt \cfrac{9!}{6!3!}=\cfrac{9\cdot8\cdot7\cdot6!}{6!\cdot3!}= \cfrac{9\cdot8\cdot7}{3\cdot2\cdot1}=3\cdot4\cdot7=84$
