Solution - Base conversion

2, 281

2,281

Step-by-step explanation

${(8 E 9)}_{16} = b a s e 10$

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

${(8 E 9)}_{16} = 8 \cdot 16^{2} + 14 \cdot 16^{1} + 9 \cdot 16^{0}$

$8 \cdot 16^{2} + 14 \cdot 16^{1} + 9 \cdot 16^{0} = 2281$

Expand each digit by place value: $8 \cdot 16^{2}$
+ $14 \cdot 16^{1}$
+ $9 \cdot 16^{0}$ . This gives $2, 281$ in base 10.

$\frac{2281}{10} = 228 r e m a \in d e r 1$

$\frac{228}{10} = 22 r e m a \in d e r 8$

$\frac{22}{10} = 2 r e m a \in d e r 2$

$\frac{2}{10} = 0 r e m a \in d e r 2$

$1 \to 8 \to 2 \to 2 = 2281$

$2281 (b a s e 10) = {(2281)}_{10}$

Repeatedly divide $2, 281$ by $10$ , collect remainders, and read them in reverse to get $2, 281$ .
