example: multiply square root of 8 times square root of 5

 can be simplified to   and again to

Step 2: Multiply the numbers


 Becomes  and that is your answer!


Step 1: simplify either of the square roots

 can be broken down  :  =  =

Step 2: multiply the numbers outside of the radical and then the numbers inside the radical

-12 times 6 will be 72

-2 times 3 comes out to 6

-The result will be
