you mean the answer should be \[\frac{ 1 }{ 2\sqrt{10x^98x^7} }\]

your answer was almost correct, the 3/2 should have been 1/2 to indicate a sqrt

ok your saing that the answer I posted previously was correct but the denominator needs to be square rooted

yes, .. or another way to write a sqrt is with an exponent of 1/2 .... not 3/2
