Answer 2

2,62×13,58=35,5796   3,8×13,58=51,604   6,42^2=41,2164
35,5796+51,604+41,2164=128,4

Answer 3

To calculate the expression, let's break it down step by step:

1. Multiply 2.62 by 13.58: 2.62 * 13.58 = 35.6116

2. Multiply 3.8 by 13.58: 3.8 * 13.58 = 51.724

3. Calculate the square of 6.42: 6.42^2 = 41.2164

4. Add the results together: 35.6116 + 51.724 + 41.2164 = 128.551

Therefore, the value of the expression 2.6213.58+3.813.58+6.42^2 is 128.551.
