9√'14-8√'14
To simplify this expression, we can combine like terms.
First, let's simplify the square roots:
√14 = √(2 * 7) = √2 * √7
Now we can rewrite the expression as:
9√2 * √7 - 8√2 * √7
The square root terms (√2 * √7) are the same, so we can combine the coefficients:
(9 - 8)√2 * √7
Simplifying further, we have:
1√2 * √7
Finally, we can rewrite the square root term as:
√(2 * 7) = √14
Therefore, the simplified expression is:
√14
