Question

$(9x {}^{3} - 8x + 7)(3x {}^{5} + 5)$
Obtain the differential coefficient .....​

Answer 1

$(9x {}^{3} - 8x + 7)(3x {}^{5} + 5) \\ = > 27x {}^{8} + 45x {}^{3} - 24x {}^{6} - 40x + 21x {}^{5} + 35 \\ = > 27x {}^{8} - 24x {}^{6} + 21x {}^{5} + 45x {}^{3} - 40x + 35$

I think it will be your answer.

If it will not I will try next time.
