a license plate has 2 letters followed by 4 digits.how many license plates are possible if the digits and letters can be repeated?

about 21 letters

10 digits 0,1 ... 9

21*21 = 441
10^4 = 10,000
so I get
4,410,000

but these are the only answers and there is 26 letters in the alphabet

sorry, yes, 26

so 26 * 26
if the letters and numbers can be repeated, that is what I get

If they could not be repeated then

26*25 * 10*9*8*7 = 3,276,000

but these r the only choices

a-8
b-92
c-676000
or
d-6760000
so what would it be

I can not make it come out to one of those choices.

the letters and numbers can be repeated, so it would be

26*26*10*10*10*10.

there are 2 spaces for letters with 26 choices and 4 spaces for digits with 10 choices.
so, your answer is 6760000
