What is the first differential of #y = t^(3/2)(16-sqrtt)#? Calculus Basic Differentiation Rules Chain Rule 1 Answer Alan N. Mar 3, 2017 #dy/dt = 24sqrtt -2t# Explanation: #y = t^(3/2)(16-sqrtt)# = #16t^(3/2) - t^(1/2+3/2)# #= 16t^(3/2) - t^2# Applying the power rule to both terms: #dy/dt = 16* 3/2t^(1/2) - 2t# #= 24sqrtt-2t# Answer link Related questions What is the Chain Rule for derivatives?
