Question

How to draw and label the components of power point 2013

Answer 1

Answer:

Explanation:

Expression is 19²⁰¹³ + 11²⁰¹³ - 6²⁰¹³

for finding unit digit , first of all we have to find unit digit of all individual terms like 19²⁰¹³ , 11²⁰¹³ , 6²⁰¹³ .

Unit digit of 19²⁰¹³ : here you have to memorize that unit place of any number repeats after fourth power . Hence, we have to divide 2013 by 4 , we see remainder is 1 hence, unit digit of 19¹ = 9

similarly unit digit of 11²⁰¹³ = unit digit of 11¹ = 1

until digit of 6²⁰¹³ = unit digit of 6¹ = 6

Now, unit digit of 19²⁰¹³ + 11²⁰¹³ - 6²⁰¹³ = unit digit of 19²⁰¹³ + unit digit of 11²⁰¹³ - unit digit of 6²⁰¹³ = 9 + 1 - 6 = 4

Hence, answer is 4
