\((2464)^{1793} \times (615)^{317}\times (131)^{491}\) के गुणनफल में इकाई स्थान पर कौन सा अंक होगा ?
Correct Answer:
A (0)
Detailed Solution:
\((2464)^{1793} \times (615)^{317}\times(131)^{491}\)
41 = 4 = 4
42 = 16 = 6
43 = 64 = 4
\((2464)^{1793} \times (615)^{317}\times(131)^{491}\)
Odd power
Unit digit 4 X 5 X 1 = 20
=> 20 = 0 Unit
\((2464)^{1793} \times (615)^{317}\times(131)^{491}\)
41 = 4 = 4
42 = 16 = 6
43 = 64 = 4
\((2464)^{1793} \times (615)^{317}\times(131)^{491}\)
विषम घात
इकाई अंक 4 X 5 X 1 = 20
=> 20 = 0 इकाई
