Express the integral as a limit of Riemann sums using right endpoints. Do not evaluate the limit$.$

${\displaystyle \underset{4}{\overset{6}{}}}\sqrt[\phantom{2}]{7x^2}dx$

Find the width of each subinterval in terms of $n.$

$$ units $$

Find the $a$ th endpoint in terms of $n.$

Evaluate $f(x)=\sqrt[\phantom{2}]{7x^2}$ at the $$ th endpoint.

$f(x_1)=x_x^x$

Express the integral as the limit of Riemann sums using right endpoints.
