Question

1/2(4×5)-2³= what's the awnser

Answer 1

Explanation:

$\frac{1}{2}(4\times5)-2^3=$

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:

$=\frac{1}{2}\cdot20-2^3$

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
