Question

Help!!!!!

Answer 1

\[\int\limits_{x}^{x^4}t^4dt\]

Answer 2

\[\int\limits_{a}^{b}x^n = \left[ \frac{x^n}{n + 1} \right]_{a}^{b} = \frac{b^n - a^n}{n + 1}\]

Now you need to apply this one.

Answer 3

there is problem in above equation , \[x^{(n + 1)}\ instead \ of x^n \ and \ (b^{n + 1} - a^{n + 1}) \ instead \ of (b^n - a^ n)\]

Answer 4

so it should be (x^16-x^4)/5 right?

Answer 5

\[=\frac{ t^5 }{ 5 }~from x \to x^4=\frac{\left( x^4 \right)^5-x^5 }{ 5 }=\frac{ x^{20}-x^5 }{ 5 }=\frac{ x^5\left( x^{15}-1 \right) }{ 5 }\]

Answer 6

says it isn't right
