8 square root 23 - square root 23
The expression can be simplified as follows:
8√23 - √23 = (8 - 1)√23 = 7√23
To subtract √23 from 8√23, we need to combine the terms that have the same radical. In this case, both terms have the square root of 23.
8√23 - √23 = (8 - 1)√23 = 7√23
So, 8√23 - √23 simplifies to 7√23.
To simplify the expression 8√23 - √23, we can combine like terms.
The terms √23 and √23 are like terms because they both have the same radical (√23). Therefore, we can subtract them.
When subtracting like terms, we subtract the coefficients (numbers in front) and keep the radical (√23) the same.
In this case, we have 8√23 - √23. The coefficients are 8 and 1.
8 - 1 = 7
So, the simplified expression is 7√23.
To calculate the answer, follow these steps:
Step 1: Subtract the coefficients: 8 - 1 = 7.
Step 2: Keep the radical (√23) the same.
Thus, 8√23 - √23 = 7√23.
