1.	Genius can answere this question .......determine the fourth derivative of given function
Answer» ANSWER: 2520t³-144 Given: $h(t)=3t^{7}-6t^{4}+8t^{2} -12t+18$ Formula USED: $x^{n}=nx^{n-1}$ EXPLANATION: First DERIVATIVE, $h'(t)=73t^{6}-64t^{3}+28t^{1} -12\\ h'(t)=21t^{6}-24t^{3}+16t -12$ Second derivative, $h''(t)=216t^{5}-243t^{2}+16\\h''(t)=126t^{5}-72t^{2}+16\\$ Third derivative, $h'''(t)=1265t^{4}-722t^{1}\\h'''(t)=630t^{4}-144t^{}\\\\$ Fourth derivative, $h^{4} (t)=6304t^{3}-144t^{1}\\ h^{4} (t)=2520t^{3}-144$
