Question

r(x)=2√x s(x)=√x (rs)(4)

Answer 1

$rs(x) = r(x) \times s(x)$
$rs(x) = 2x$
$rs(4) = 8$

Answer 2

r(x)=2√x s(x)=√x (rs)(4); The values of r(s) in the given question is 8

From the given information;

$\mathbf{r(x) = 2\sqrt{x}}}$

$\mathbf{s(x) = \sqrt{(x)}}$

The multiplication of $\mathbf{(rs)(x) = 2\sqrt{(x)} \ \times \ \sqrt{x} }$

$\mathbf{(rs)(x) = 2\sqrt{(x) ^2}}$

When the square root is being squared, both entities cancel out each other.

Having said that; $\mathbf{(rs)(x) = 2(x) }}$

Now, the solution of (rs)(4) = 2(4)

$\mathbf{ (rs)(4) = 8}$

Therefore, we can conclude that the solution to the equation (rs)(4) is 8.
