Your answer :
You are correct. In expansions such as
368  = 3(81) + 6(80)  = 3(8) + 6(1)  = 2410 + 610  = 3010.
all of the numbers on the right-hand of the equal (=) sign are meant to be read as decimal numbers. We have not always shown the decimal subscript on such expressions as 3(81). But
is a complicated way of saying it. You’ll have to remember that if no subscript is shown, the number is meant to be read as a decimal number.
