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.
