Answer 2

The answer for the given question is -36.764.

Step-by-step explanation:

• Given: √2 = 1.414.
• To solve: 3√32 - 2√50 + 4√128 - 20√18.

        Solution:

• The first step is to find the factors of the given numbers.
• Step 1: 3√32 = 3√2×2×2×2×2 = 12√2.
• Step 2: 2√50 = 2√2×5×5 = 10√2.
• Step 3: 4√128 = 4√2×2×2×2×2×2×2= 32√2.
• Step 4: 20√18 = 20√2×3×3 = 60√2.
• Substituting all the steps, we get  

        3√32 - 2√50 + 4√128 - 20√18 = 12√2 - 10√2 + 32√2 - 60√2.

                                                             = 44√2 - 70√2

                                                             = - 26√2

                                                             = - 26 × 1.414  

                                                             = - 36.764.

• Hence, the answer is - 36.764.
