Answer 2

• Given: √3 = 1.732.
• To solve: √27 + √75 + √108 - √243.

        Solution:

• The first step is to find the factors of the given numbers.
• Step 1: √27 = √3×3×3 = 3√3.
• Step 2: √75 = √3×5×5 = 5√3.
• Step 3: √108 = √3×3×2×3×2 = 6√3.
• Step 4: √243 = √3×9×9 = 9√3.
• Substituting all the steps, we get  

    √27 + √75 + √108 - √243 = 3√3 + 5√3 + 6√3 - 9√3

                                                = 14√3 - 9√3

                                                = 5√3

                                                = 5 × 1.732  

                                                = 8.66.

• Hence, the answer is 8.66.
