2 thirds times 4 is 8 thirds. So it's plus 8 thirds times y plus 1 to the 3 halves. And you can verify, if you take the derivative here, you will get this expression right over here. 3 halves times 8 thirds is 4. Decrement it, you have y plus 1 to the 1 half power. And then finally, you have this 5. The antiderivative of 5 is just 5y.
