Integrate the following: ∫<img src="https://tex.z-dn.net/?f=5x%5E4dx" id="TexFormula1" title="5x^4dx" alt="5x^4dx" align="absmid
Fiesta28 [93]

Answer:

A. x^5+C

Step-by-step explanation:

This is a great question! The first thing we want to do here is to take the constant out of the expression, in this case 5. Doing so we would receive the following expression -

5\cdot \int \:x^4dx

We can then apply the power rule " \int x^adx=\frac{x^{a+1}}{a+1} ", where a = exponent ( in this case 4 ),

5\cdot \frac{x^{4+1}}{4+1}

From now onward just simplify the expression as one would normally, and afterward add a constant ( C ) to the solution -

5\cdot \frac{x^{4+1}}{4+1}\\ - Add the exponents,

5\cdot \frac{x^{5}}{5} - 5 & 5 cancel each other out,

x^5 - And now adding the constant we see that our solution is option a!
