Answer:
The correct answer is 30x √ 2y
Step-by-step explanation:
Let's multiply:
√6x * √15xy * √20
Let's recall that √a * √b * √c = √(a * b * c), therefore we have:
= √ (6x * 15 xy * 20)
= √1,800x²y
= √900*2 x²y (Factoring 1,800 in 900 * 2)
= 30x √ 2y
This is the most simplified expression.
The correct answer is 30x √ 2y
