$4.1xx10^7$

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

$3-2"; "4/4"; " sqrt5/sqrt5"; " 10/10"; "10^7/10^7$

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

$41,000,000xx10^7/10^7$

Write this as:

$(41,000,000)/(10^7) xx10^7$

$4.1xx10^7$

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