Question 31
a.

Determine ∫(10t4−6t3) dt\int \left( 10t^4 - \frac{6}{\sqrt[3]{t}} \right) \, dt ∫(10t4−3t​6​)dt.

b.

The rate of change of the mass, MMM grams, of a synthetic crystal with respect to time, ttt hours, is modeled by the differential equation

dMdt=10t4−6t3,t>0 \frac{dM}{dt} = 10t^4 - \frac{6}{\sqrt[3]{t}}, \quad t > 0 dtdM​=10t4−3t​6​,t>0

After 8 hours of growth, the mass of the crystal is measured to be 65520 grams.

Find an expression for MMM in terms of ttt.
