- x=y1/7,0y2x = y ^ { 1 / 7 } , 0 \leq y \leq 2


A) 02149y12/7dy\int _ { 0 } ^ { 2 } \sqrt { \frac { 1 } { 49 y ^ { 12 / 7 } } } d y
B) 02249y12/7dy\int _ { 0 } ^ { 2 } \sqrt { \frac { 2 } { 49 y ^ { 12 / 7 } } } d y
C) 027y6/7+17y6/7dy\int _ { 0 } ^ { 2 } \sqrt { \frac { 7 y ^ { 6 / 7 } + 1 } { 7 y ^ { 6 / 7 } } } d y
D) 0249y12/7+149y12/7dy\int _ { 0 } ^ { 2 } \sqrt { \frac { 49 \mathrm { y } ^ { 12 / 7 } + 1 } { 49 \mathrm { y } 12 / 7 } } d y
