Question

29²=(30-1)²=79²9,8²4,7²​

Answer 1

29²=29·29=841
79²=79·79=6241
9,8²=(49/5)²
4,7²=(47/10)²

Answer 2

Let's break down the equation step by step:

29² = 29 * 29 = 841

(30 - 1)² = 29² = 841

79² = 79 * 79 = 6241

9,8² = 9.8 * 9.8 = 96.04

4,7² = 4.7 * 4.7 = 22.09

Therefore, the equation can be simplified as:

29² = (30 - 1)² = 79² = 6241 = 9,8² = 96.04 = 4,7² = 22.09
