Express in simplest radical form.
10√7 - √7
9√7
To express this expression in simplest radical form, we combine like terms. In this case, we have 10√7 - √7.
Since both terms have the same radical (√7), we can simply subtract their coefficients. The coefficient of the first term is 10, and the coefficient of the second term is 1. Therefore, our simplified expression becomes:
10√7 - √7 = (10 - 1)√7 = 9√7
So, the expression 10√7 - √7 simplifies to 9√7 in simplest radical form.
To express the expression 10√7 - √7 in the simplest radical form, we can simplify it by combining the terms that have the same radical.
We have two terms, 10√7 and -√7, both containing the square root of 7 (√7).
Since both terms have the same radical (√7), we can combine them by subtracting their coefficients:
10√7 - √7 = (10 - 1)√7
Simplifying further:
(10 - 1)√7 = 9√7
Therefore, the expression 10√7 - √7 simplified in the simplest radical form is 9√7.
