Answer» माना `y=x^5-9x^(4)-15x^3+6x^(2)-17x+9` `therefore (dy)/(dx)=(d)/(dx)(x^(5)-9x^(4)-15x^(3)+6x^(2)-17x+9)` `=(d)/(dx)x^5-9(d)/(dx)x^(4)-15(d)/(dx)x^(3)+6(d)/(dx)x^(2)-17(d)/(dx)x+(d)/(dx)9` `=5x^(5-1)-9(4x^(4-1))-15(3x^(3-1))+6(2x^(2-1))-17(d)/(dx)x+(d)/(dx)9` `=5x^(5-1)-9(4x^(4-1))-15(3x^(3-1))+6(2x^(2-1))-17(1x^(1-1))+0` `=5x^(4)-36x^(3)-35x^(2)+12x-17` |
