Solution - Base conversion

3, 309

3,309

Step-by-step explanation

${(C E D)}_{16} = b a s e 10$

Identify the source number, source base, and target base before converting through base 10.

${(C E D)}_{16} = 12 \cdot 16^{2} + 14 \cdot 16^{1} + 13 \cdot 16^{0}$

$12 \cdot 16^{2} + 14 \cdot 16^{1} + 13 \cdot 16^{0} = 3309$

Expand each digit by place value: $12 \cdot 16^{2}$
+ $14 \cdot 16^{1}$
+ $13 \cdot 16^{0}$ . This gives $3, 309$ in base 10.

$\frac{3309}{10} = 330 r e m a \in d e r 9$

$\frac{330}{10} = 33 r e m a \in d e r 0$

$\frac{33}{10} = 3 r e m a \in d e r 3$

$\frac{3}{10} = 0 r e m a \in d e r 3$

$9 \to 0 \to 3 \to 3 = 3309$

$3309 (b a s e 10) = {(3309)}_{10}$

Repeatedly divide $3, 309$ by $10$ , collect remainders, and read them in reverse to get $3, 309$ .
