Question

1/2(4×5)-2³= what's the awnser

Answer 1

Step-by-step explanation:

`(1)/(2)(4*5)-2^3=`

First we have to solve the products, divisions and powers in each term. The terms are separated by + or - signs. In this expression there are two terms.

In the first term there's a product inside a parenthesis. This means that we have to solve that first:

`=(1)/(2)\cdot20-2^3`

Now we can solve the multiplication in the first term:

`=10-2^3`

Solve the power in the second term:

`=10-8`

And do the substraction:

`=2`

Answer:

1/2(4x5) - 2³ = 2
