Could someone please help me with this math problem? This is what I have so far but now I am stumped as to what to do next.

Multiply and simplify by factoring.
The square root of 18 * square root of 40.
The square root of 18= the square root of 9*2. The square root of 9 * square root of 2= square root of 3 * square root of 2.
Now for the square root of 40. 2* the square root of 10.
This is where I am stumped. What do I do next?
Thanks for the help.

Never mind I figured out the answer.

To simplify the expression, you can now multiply the simplified square root terms:

Square root of 3 * square root of 2 * 2 * square root of 10

Multiplying these terms together, you can combine the square roots of the same number and simplify:

= (square root of 3 * 2) * (square root of 2 * square root of 10)

= square root of 6 * square root of 20

Now, you can simplify further by factoring the numbers inside the square roots:

= square root of 6 * (square root of 4 * square root of 5)

Since the square root of 4 is a whole number (2), you can simplify it further:

= square root of 6 * 2 * square root of 5

Lastly, you can multiply the whole numbers together:

= 2 * square root of 6 * square root of 5

Therefore, the simplified expression is:

2 * square root of 6 * square root of 5
