To determine
To find:
The integral of ∫243xdx.
Answer
0.301.
Given: ∫243xdx
Formulae used:
∫1xdx=logx∫xadx=xa+1a+1
loga−logb=logab
Explanation
Consider y=∫243xdx=3∫241xdx.
Use the formula ∫1xdx=logx
So,
y=[logx]24=log4−log2=log42=log2
=0.301
Conclusion:
Hence, the solution of the given function is 0.301.
