The sum of given expression ![\sqrt[3]{125}x^{10}y^{13}+\sqrt[3]{27}x^{10}y^{13}](/tpl/images/0138/4721/e5293.png)
is Β 
Step-by-step explanation:
Β Given : expression
We have find the sum of given expression
Consider the given expression
![\sqrt[3]{125}=\sqrt[3]{5\times 5 \times 5}=\sqrt[3]{5^3}](/tpl/images/0138/4721/1eda1.png)
Apply radical rule, ![\sqrt[n]{a^n}=a](/tpl/images/0138/4721/b69f6.png)
we have, ![\sqrt[3]{125}=\sqrt[3]{5^3}=5](/tpl/images/0138/4721/53c3c.png)
Also, Β ![\sqrt[3]{27}=\sqrt[3]{3\times 3 \times 3}= \sqrt[3]{3^3}](/tpl/images/0138/4721/50704.png)
Apply radical rule,
we have, ![\sqrt[3]{27}=\sqrt[3]{3^3}=3](/tpl/images/0138/4721/302e5.png)
Thus, given expression becomes,
Simplify, we get,
Thus, the sum of given expression is Β
