    √240 - √12 X √45=√(16*15)-√(9*15)=4√15-3√15=√15

    \/12 X \/45 = \/540

    \/540 = \/ 36* 15 = 6\/15

    \/240 = \/ 16*15 = 4\/15

    4\/15 - 6\/15 = - 2\/15 ANSWER

    sqrt 240 = sqrt 16 x sqrt 15 = 4sqrt15

    (sqrt12 x sqrt45) = sqrt 540 = sqrt 15 x sqrt 36 = 6sqrt15

    4sqrt15 - 6sqrt15 = -2sqrt15
