THe cube root of 5 to the 2.7th power devided by 5 to the 1.5th power??
Please help me im really lost with this
 
If you are supposed to simplify it, you could change the cube root to a power of (1/3) and use exponent rules.
 
Okay,

so since under the cube root symbol the division problem involves the same bases you could use 5^2.7 divided by 5^1.5 and get 5^1.2 by subracting the exponents when the bases are the same. Then you would have the cube root of 5^1.2

Rewriting the cube root as an expeonent of 1/3 gives you this

(5^1.2)^(1/3) so now all you need to do is multiply the 1.2 by (1/3) and either choose to leave you answer as 5^ a decimal or 5^ a fraction.
