Reduce the rational expression to lowest terms
1/15abc (5a^3b^5c^2)
=3a^2b^4c
Is this right. I reduced,and cancelled out exponents.

algebra 
PsyDAG,
1/15abc (5a^3*b^5*c^2)
"*" indicates multiplication. Combine the a,b and c terms.
1/15(5a^4*b^6*c^3) = 1/3 (a^4*b^6*c^3)
Since the 15 is in the denominator, I don't know hw you got 3 ratherthan 1/3.
However, if the formula is
1/(15abc)*(5a^3*b^5*c^2) =
1/3 (a^2*b^4*c)
Without the multiplication indicators, your answer is unclear as to whether it is b^4*c or b to the 4c power.
You need to make your formulas clearer.
I hope this helps. Thanks for asking.
