    \[{3\over4}x\times{1\over9}x\]multiply straight across (3 times 1, 4 times 9, x times x):\[{3\over36}x^2\]simplify:\[{1\over12}x^2\]this can also be written as:\[x^2\over12\]:) hope this helps :)

    sry if it looked wrong on the 1st drawing :). pretty sure you just multiply the fractions and it becomes x^1/12 right?

    oh im sorry :O okay so you have to add the exponents :) \[\huge x^{3\over4}\times x^{1\over9}\]so find the common denominator:\[\huge x^{27\over36}\times x^{4\over36}\]now add:\[\huge x^{31\over36}\] when multiplying you add the exponents :)
