Let's from the numbers from their expanded from given below:-
`8 xx 10^4 + 2 xx 10^3 + 3 xx 10^2 + 6 and 9 xx 10^4 + 5 xx 10^3 + 6 xx 10^2 + 7 xx 10`

Let's from the numbers from their expanded from given below:- 2xx 10^3 + 3 xx 10 +5

Let's from the numbers from their expanded from given below:- 3 xx 10^3 + 2 xx 10^2 + 7 xx 10 +2

Solve:- 10^5 xx 10^2 = ?

Let's complete the table given below: (-6) xx (-10) + (-4) xx 4 = ?

Let's fill in the blank squares given below:- 10^2 = ?xx ?
