    You can simplify the radical parts and the integer parts... Think of it like this and simplify each part: (8/6)(√49/√7) = (4/3)(√7/1) = (4√7)/3 I hope that helps! Keep working hard on your math! :-)

    so anytime your multiplying radicals let's say (√7x)(√2x) would that be √14x^2 or would it be √14x since x to the power of one multiplied by x to the power of one =1
