Is this x^(1/12)

3. anonymous

cross multiply

4. anonymous

${3\over4}x\times{1\over9}x$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 :)

|dw:1354493673382:dw| that's what I meant :)

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 :)
