Answer:
The correct answer would be 40
Step-by-step explanation:
To find two square roots being multiplied together, you can multiply the numbers beneath the symbol.
√2 x √800 = √1600
Now you can perform the square root operation.
√1600 = 40
40
√2 x √800
We know that sqrt(a) * sqrt(b) = sqrt(ab)
sqrt(1600)
sqrt(16) sqrt(100)
4*10
=40
