Exercise 9.6.1: Converting from non-decimal bases to decimal. Compute the decimal representation for each of the following numbers. (b) (346)7 (d) (120121)3 (f) (50020)8
Added by Ashley R.
Step 1
(b) To convert (346)7 to decimal, we can use the formula: (346)7 = 3 * 7^2 + 4 * 7^1 + 6 * 7^0 Calculating the values: (346)7 = 3 * 49 + 4 * 7 + 6 * 1 (346)7 = 147 + 28 + 6 (346)7 = 181 So, (346)7 = $\boxed{181}$ in decimal. Show more…
