Question about subscripts

[miket]

Am preping for a test and have the following formula and the solution, but don't understand how you really solve for X

32 = x
4 2

where the answer is 1110

First setp per the guide is:

1 0
3 x 4 + 2x 4 = 14

then
3 2 1 0
14 = 1x2 + 1x2 + 1x2 + 0x 2

so the answer is 1110

Help?

Wow your post is very confusing. Hopefully someone else can decipher it.

In this case, we just have a formatting problem. The secret it in the title.

\(\displaystyle \L\,32_{4} = x_{2}\)

Translating

3*4 + 2 = 12 + 2 = 14 -- Base 10

What is that, Base 2?

reformatted w/ latex ...

\(\displaystyle \L 32_4 = x_2\)

where the answer is 1110

First setp per the guide is:

\(\displaystyle \L 3 \times 4^1 + 2 \times 4^0 = 14\)

then

\(\displaystyle \L 14 = 1 \times 2^3 + 1 \times 2^2 + 1 \times 2^1 + 0 \times 2^0\)

so the answer is 1110

Help?

miket ... all the example did was change 32 from base 4 to 14 base 10, then change 14 base 10 to 1110 base 2.
