i think it is i am i correct thank you for helping me

• math check my work - ,

10 digits 0,1 ... 9

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

• math check my work - ,

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

• math check my work - ,

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

• math check my work - ,

If they could not be repeated then
26*25 * 10*9*8*7 = 3,276,000

• math check my work - ,

but these r the only choices
a-8
b-92
c-676000
or
d-6760000
so what would it be

• math check my work - ,

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

• math check my work - ,

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.
