You need to know the basic rules of powers:\[a^{b}=\frac{ 1 }{ a^b }\]\[a^{\frac{ ^b }{ c }} =\sqrt[c]{a^b}=(\sqrt[c]{a})^b\]\[(a^b)^c=a^{bc}\]\[a^b \cdot a^c=a^{b+c}\]\[\frac{ a^b }{ a^c }=a^{bc}\] Try to see what you need to do with these rules here...

5 root 64x^26 in case the other post was hard to read

I got to: \[(64x^6)^{\frac{ 5 }{ 3 }}=\frac{ 1 }{ (64x^6)^{\frac{ 5 }{ 3 } }}=\frac{ 1 }{ 64^{\frac{5}{3}}x^{6 \cdot \frac{5}{3}} }=\frac{ 1 }{64^{\frac{5}{3}} x^{10}}\]Now we have that nasy 64^(5/3)... But 64=2^6! so we can go a bit further:\[\frac{ 1 }{ (2^6)^{\frac{5}{3}} x^{10}}=\frac{ 1 }{ 2^{10}x^{10} }=\frac{ 1 }{ 1024x^{10} }\]

Once you've seen it again, you'll remember...just practise a few more and you're safe!
