Question

Find tha differention of -¾x⁴ -8x³-45½x²+105

Answer 1

Answer:

$-3x^{3} -24x^{2} -45x$

Step-by-step explanation:

now differentiation of        $x^{n} =nx^{n-1}$

$x^4=4x^3\\similarly \ x^3=3x^2\\\\x^2=2x\\\\and\ differentiation\ of\ constant\ term\ is\ zero.\\\\now \ put\ these\ values\ in\ the\ equation\ and\ get\\\\-\frac{3}{4}\times4x^3-8\times3x^2-\frac{45}{2} \times 2x+0\\so\ answer\ is -3x^3-24x^2-45x$
