Your answer :
1( 82 ) + 3( 81 ) + 2( 80 ) = 104.
Where did you get off the track?
1( 82 ) + 3( 81 ) + 2( 80 ) = 1( 64) + 3( 8) + 2( 1) = ?
Did you make the mistake of counting
2( 80 ) as
2( 8) = 16 ? For shame. Don’t forget the meaning of a 0 exponent:
b 0 = 1.
Now return to Page 191 and choose the correct answer.
