solve the following questions ( handwritten solution only neatly and clean box final answer) thankyou!

Evaluate the following integrals. Write your final answers with simplified numerical coefficients and with variables raised to positive constant exponents. If your answer is a radical expression, no need to convert the expression with rational exponents. Show complete solution and/or substitution for full credit.
