![c^(2)](https://img.qammunity.org/2021/formulas/mathematics/high-school/k35u7m6yuyioehiuxbng19npestgihit5x.png)
So, what's 41 to the power 2?
Thus;
1,681
Do the same for the other one.
9 to the power of 2
Thus;
81
Add all these up all your final answer to get a total of 1,762.
1681+81=1762
Thus;
![c^(2) = 1762](https://img.qammunity.org/2021/formulas/mathematics/high-school/qh3ijqoai085ilew339uvzxrg3j2nrwuwh.png)
Then square root your final answer
=
![c^(2)](https://img.qammunity.org/2021/formulas/mathematics/high-school/k35u7m6yuyioehiuxbng19npestgihit5x.png)
Thus;
42=
