### 1. Map the unsigned binary number's digits versus the corresponding powers of 2 that their place value represent:

2^{15}

1 2^{14}

0 2^{13}

1 2^{12}

1 2^{11}

1 2^{10}

0 2^{9}

1 2^{8}

0 2^{7}

0 2^{6}

1 2^{5}

1 2^{4}

0 2^{3}

1 2^{2}

0 2^{1}

0 2^{0}

1

### 2. Multiply each bit by its corresponding power of 2 and add all the terms up:

#### 1011 1010 0110 1001_{(2)} =

#### (1 × 2^{15} + 0 × 2^{14} + 1 × 2^{13} + 1 × 2^{12} + 1 × 2^{11} + 0 × 2^{10} + 1 × 2^{9} + 0 × 2^{8} + 0 × 2^{7} + 1 × 2^{6} + 1 × 2^{5} + 0 × 2^{4} + 1 × 2^{3} + 0 × 2^{2} + 0 × 2^{1} + 1 × 2^{0})_{(10)} =

#### (32 768 + 0 + 8 192 + 4 096 + 2 048 + 0 + 512 + 0 + 0 + 64 + 32 + 0 + 8 + 0 + 0 + 1)_{(10)} =

#### (32 768 + 8 192 + 4 096 + 2 048 + 512 + 64 + 32 + 8 + 1)_{(10)} =

#### 47 721_{(10)}
