    The bottom one's a formula book one, take out a factor of 3 (root 9) on the bottom line and compare with the standard one in the formula book.

    The top one, split into two fractions, the x/(9x² - 16)^1/2 you use a substitution of u = 9x² - 16 and the other fraction is the first one which you do the way I said above.
