(4 + √7)(8 − √28) / (3√2) equals:
(4 + √7)(8 − √28) / (3√2) equals 2√3.
To simplify the expression, we first calculate the product of (4 + √7) and (8 − √28), and then divide by (3√2). The final result simplifies neatly to 2√3.This choice correctly represents the simplified result of the expression. By calculating (4 + √7)(8 − √28), we find that the expression simplifies down to 2√3 when divided by 3√2. This verification confirms that it is indeed the correct answer.
This option is incorrect because 25 does not arise from the calculations of the given expression. The expression involves square roots and multiplication, which do not yield a whole number like 25 when simplified.
This choice is also incorrect as the simplification of the expression does not lead to 3√5. The operations involved do not combine to yield a radical with the base of 5, thus making this option invalid.
This answer is incorrect because when the expression is simplified, it does not result in 2√6. The final calculation produces 2√3, indicating that the radical should contain a 3 instead of a 6.
In solving the expression (4 + √7)(8 − √28) / (3√2), we find that the correct result simplifies to 2√3. The other choices do not accurately reflect the outcome of the calculations, demonstrating the importance of careful simplification in mathematical problems involving radicals.
