Simplify.
√2 times √8
To simplify this expression, we use the property of radicals that states √a * √b = √(a * b). Applying this property, we can write the expression as:
√2 * √8 = √(2 * 8)
Next, we simplify the multiplication:
√(2 * 8) = √16
Finally, we simplify the square root:
√16 = 4
Therefore, √2 times √8 simplifies to 4.
