Subtract 8√23−√23 .

Answer 1

To simplify the expression \( 8\sqrt{23} - \sqrt{23} \), you can combine the like terms.

Both terms involve \( \sqrt{23} \).

1. The coefficient of the first term is 8 and the coefficient of the second term is -1.
2. Combine the coefficients:

\[ 8 - 1 = 7 \]

3. Therefore, the expression simplifies to:

\[ 7\sqrt{23} \]

So, \( 8\sqrt{23} - \sqrt{23} = 7\sqrt{23} \).
