-18

Step-by-step explanation: Simplify it this way, they are both radicals, so it is easy to multiply them.

(6) * (-3) 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
