Question

which two Signs Should be Interchanged in the following equations to make it correct 8*2+5-16÷4=14​

Answer 1

Step-by-step explanation:

8 × 2 + 5 - 16 ÷ 4 = 14

8 × 2 + 5 - 4 = 14

16 + 5 - 4 = 14

21 - 4 = 14

17 = 14

So, this equation is not correct.

Answer 2

Answer:

* and + signs should be interchanged to make the given equation correct.

Step-by-step explanation:

Consider the given equation as follows:

8 * 2 + 5 - 16 ÷ 4 = 14

Compute the left-hand side as follows:

⇒ 8 * 2 + 5 - 16 ÷ 4

Using the BODMAS rule, we get

⇒ 8 * 2 + 5 - 4 (Applying division rule)

⇒ 16 + 5 - 4 (Applying multiplication rule)

⇒ 21 - 4 (Addition rule)

⇒ 17

Notice that LHS ≠ RHS.

We need to interchange two signs to make the equation correct.

Interchange the signs + and *, we get

8 + 2 * 5 - 16 ÷ 4

Now, simplify using BODMAS as follows:

⇒ 8 + 2 * 5 - 4

⇒ 8 + 10 - 4

⇒ 18 - 4

⇒ 14

This implies LHS = RHS.

Therefore, * and + signs should be interchanged to make the given equation correct.
