Solve this expression 8÷2*5+(6-4)

Annette [7]

Value of expression $\frac{8}{2}(5) + (6-4)$ is 22 .

<u>Step-by-step explanation:</u>

Here we have the following expression to solve :

8÷2*5+(6-4)

⇒ $(8/2)*5 + (6-4)$

⇒ $\frac{8}{2}(5) + (6-4)$

But 8 = 4(2) , So

⇒ $\frac{4(2)}{2}(5) + (6-4)$

⇒ $4(5) + (6-4)$

⇒ $20 + (6-4)$

⇒ $20 + 2$

⇒ $22$

Therefore, Value of expression $\frac{8}{2}(5) + (6-4)$ is 22 .
