Answer 2

Answer:

The interchangable two numbers are 8 and 12

Step-by-step explanation:

After we change 8 and 12 equation will be

25×4-9×8+12=40

⇒100-72+12=40

⇒100-60=40

⇒40=40.

Satisfied. And equation is True.

Using BODMAS RULE , we calculate this type of math equations.

What is BODMAS RULE?

B - Brackets - ( )    like 66+(42÷2)⇒ 66+21

O - Order     - $2^{2}$,$3^{2}$ like 4+$2^{2}$+6⇒4+4+6⇒14

D - Division  - 24/8 like 16+24/8⇒16+3

M - Multiplication - 25×4 like 2+25×4⇒2+100

A - Addition - 5+25 like 5+2-3⇒7-3

S - Subtraction - 20-10 like 4-3⇒1

We must follow the order to calculate these type of math equation
