Multiply (√7) (−√2) . Give an exact answer.(1 point)
The product of (√7) and (−√2) can be found by multiplying the numerical parts and keeping the square roots:
(√7) (−√2) = -√(7*2) = -√14
So, the exact answer is -√14.
To multiply (√7) and (-√2), we can use the property of square roots that states √a * √b = √(a * b).
Therefore, (√7) * (-√2) = -√(7 * 2).
Simplifying further,
-√(7 * 2) = -√14.
So, the exact answer is -√14.
To multiply (√7) and (-√2) and find the exact answer, we can use the product rule for square roots. The product rule states that √a * √b = √(a * b).
In this case, we have (√7) * (-√2). Using the product rule, we can multiply the numbers under the square roots together:
√(7 * 2)
Simplifying the expression inside the square root:
√14
So, the exact answer to (√7) * (-√2) is √14.
