The exponent of in is
- A
- B
- C
- D
Answer & Solution
Correct Answer
(A)
Step-by-step Solution
Detailed explanation
To find the exponent of 6 in 72! we will find exponent of 2 & 3, So exponent of 2 is given by, 722+7222+7223+7224+7225+7226 =36+18+9+4+2+1=66 {where . is greastest integer function} Now finding the exponent of 3 in 72! we get, 723+7232+7233=24+8+2=34 Now we know…
