Answer:
7x * √(x^2/49) - 7x = 7x * (√(x^2/49) - 1)
And this is as far as we can simplify the expression.
Explanation:
To multiply these terms, we can use the distributive property:
√7x * (√x - 7√7) = √7x * √x - √7x * 7√7
Now we can simplify:
√7x * √x - √7x * 7√7 = √(7x * x) - √(7x * 49)
This simplifies to:
√(7x * x) - √(7x * 49) = √(49x^2) - 7x
If we want to simplify further, we can rewrite the expression as:
√(49x^2) - 7x = 7x * √(x^2/49) - 7x
This simplifies to:
7x * √(x^2/49) - 7x = 7x * (√(x^2/49) - 1)
And this is as far as we can simplify the expression.
