Convert 10010000. To a numeral in base10
2
I assume that 10010000 is a binary number. To transform this number to a decimal system, take each "1" and count how many positions to the left it is and multiply by the base 2 the expoenent of the positions minus 1. So the first 1 is equal to 2 X (the expoenent 4) or 2 to the 4th power which would be 16. The second 1 further to the left would be equal to 2 to the 7th power or 128. Now simply add the 16 and 128 together and you get 144.
I believe my solution is correct. However, math is not my strongest suit. Geography and History are. :)
