Answer :
Final answer:
The expression 5√7-4x√7-x√7 is equivalent to (5-5x)√7. This is simplification of the given expression by combining like terms.
Explanation:
To find the equivalent expression, we can simplify it by combining like terms.
The expression is
5√7 - 4x√7 - x√7
Since all three terms have the same radical, we can combine them by adding or subtracting their coefficients.
The coefficient of the first term is 5, the coefficient of the second term is -4x, and the coefficient of the third term is -x.
Combine the coefficients:
5 - 4x - x
Simplify the expression:
5 - 4x - x = 5 - 5x
Therefore, the equivalent expression is 5 - 5x.
