What is the first digit of $2^{43} $? What is the first digit of the number $2^{43}$?


I know how to do this task if it was the last digit to be calculated.
Hint: Using the fact that $2^{10}=1024=10^3\cdot(1+0.024)$ you can decompose $2^{43}=8\cdot (2^{10})^4$. I think you can take it from here.
yes it will easy to find last digit. bcoz lot of sources and many ssc and banking queation ask only last digit.
here, it is also tricky question we can break 2^43 as 2^3 *1024*1024*1024*1024 as you can see multication of 1024  four times always gives 1 as leading digit. u can see thing by breaking 1024 as 1000+24 to power 4 now you will get idea after that multiply with 8 will always give 8 as leading digit.
pls leave comment if any doubt:
