Answer: -18[tex]\sqrt{10}[/tex]
Step-by-step explanation: Simplify it this way, they are both radicals, so it is easy to multiply them.
(6[tex]\sqrt{2}[/tex]) * (-3[tex]\sqrt{5}[/tex]) can be broken down into 6 * -3 and sqrt(2) * sqrt(5). Then you put the numbers together.
6*-3 = -18
sqrt(2) * sqrt(5) = sqrt(10) (just multiply the numbers inside the square root symbol)
sqrt(10) is not equal to a whole number, so you just write the final answer as: -18[tex]\sqrt{10}[/tex]
hope this helped!
