Change the representation of 102_{5} from base five to base ten.

102_{5} = 1 × 5_{10}^{2} + 0 × 5_{10}^{1} + 2 × 5_{10}^{0}
= 25_{10} + 2_{10} = 27_{10}

Here
is another example: 326_{7}.
This means:

` 3 × seven`^{2} + 2 × seven^{1} + 6 × seven^{0}

To write the number in decimal, write the powers of seven in decimal and perform the arithmetic:

3 × 7^{2}+ 2 × 7^{1}+ 6 × 7^{0}= 3 × 49 + 2 × 7 + 6 × 1 = 147 + 14 + 6 = 167

Can 682_{7} be rewritten in base ten notation?
