$$\left(6.91\cdot {10}^{-2}\right)+\left(2.4\cdot {10}^3\right)$$

$$\left(6.91\cdot {10}^{-2}\right)+\left(2.4\cdot {10}^3\right)$$

$$\left(6.91\cdot 0.01\right)+\left(2.4\cdot {10}^3\right)$$

$$\left(6.91\cdot 0.01\right)+\left(2.4\cdot {10}^3\right)$$

$$\left(0.069\right)+\left(2.4\cdot {10}^3\right)$$

$$0.069+\left(2.4\cdot {10}^3\right)$$

$$0.069+\left(2.4\cdot 1000\right)$$

$$0.069+\left(2.4\cdot 1000\right)$$

$$0.069+\left(2400\right)$$

$$0.069+2400$$

$$2400.069$$
