$4.1 \times {10}^{7}$

#### Explanation:

Multiply a number by 1 and you do not change its value. The thing is; 1 comes in many forms:

$3 - 2 \text{; "4/4"; " sqrt5/sqrt5"; " 10/10"; } {10}^{7} / {10}^{7}$

Multiply by 1 but in the form of $1 = {10}^{7} / {10}^{7}$ giving:

$41 , 000 , 000 \times {10}^{7} / {10}^{7}$

Write this as:

$\frac{41 , 000 , 000}{{10}^{7}} \times {10}^{7}$

$4.1 \times {10}^{7}$

This is exactly the same value we started with it is just that it looks different.
