# The left column of the chart lists the lengths of input chains of gold. Repeater machines are listed across the top. The other entries are the outputs you get when you send the input chain from that row through the repeater machine from that column. Copy and complete the chart.

**Solution:**

Given, the left column of the chart lists the lengths of input chains of gold.

Repeater machines are listed across the top.

The other entries are the outputs you get when you send the input chain from that row through the repeater machine from that column.

We have to complete the chart.

We know, Input × stretching power = Output

From first row,

Input × 8 = 40

Input = 40/8 = 5

Stretching power = 125/5 = 25

From second row, 2 × 8 = 16

Input Length | Repeater Machine | ||

× 2³ | × 3³ | × 5² | |

5 | 40 | 135 | 125 |

2 | 16 | 54 | 50 |

6 | 48 | 162 | 150 |
