Let $y=x^{3000}, x=1$ and $x+\Delta x=1.0002$ Then, $\Delta x=1.0002-1=0.0002$ Also, y = 1 when x = 1 Now, $y=x^{3000}$ $\Rightarrow \frac{d y}{d x}=3000 x^{2999} \Rightarrow\left(\frac{d y}{d x}\right)_{x=1}=3000$ ∴ $\Delta y=\frac{d y}{d x} \Delta x$ $\Rightarrow \Delta y=3000 \times 0.0002=\frac{6}{10}=0.6$ Hence, $(1.0002)^{3000}=y+\Delta y=1+0.6=1.6$ |
