Question

What base makes the equation below true?

 

Note: A number should be entered, not a word.

 

62=68x, for x=______

Answer 1

Hi Bobbie,

I assume the 62 is in base 10. Then 68_x must be base 9 since

6*9+8*1 = 62.

To write a number with its base shown, use the subscript tool like this:

62₁₀ = 68₉
