Subtract 8sqrt(23) - sqrt(23) (1 point)
O 8sqrt(46)
8sqrt(23)
O 7sqrt(46)
7sqrt(23)
The correct answer is 7sqrt(23)
To subtract 8√(23) - √(23), we need to combine like terms.
√(23) is the common term in both expressions, so we can subtract them.
8√(23) - √(23) = (8 - 1)√(23) = 7√(23)
Therefore, the answer is 7√(23).
To subtract the two square roots, you need to follow these steps:
1. First, notice that both terms have the same square root, sqrt(23), so you can factor it out: sqrt(23)(8 - 1).
2. Simplify the expression inside the parentheses by subtracting the numbers: sqrt(23)(7).
3. Finally, combine the square root term with the simplified expression: 7sqrt(23).
Therefore, the correct answer is 7sqrt(23).
