Question

Can someone tell me the answers and show how you did it step by step with the parentheses and everything?

Answer 1

Solution : - 20

Explanation:

We have the following expression to simplify,

`\left\{\left[(\left(3+5\right))/(2)\right]^2-\left(3\cdot 2\right)\right\}\cdot \left(-2\right)`

Let's start by simplifying simple expressions, such as 3 + 5 = 8 and 3 * 2 = 6. Substituting we receive,

`\left\{\left[(\left(8\right))/(2)\right]^2-\left(6\right)\right\}\cdot \left(-2\right)`

8 / 2 = 4, and 4² = 16 -

`\left\{16-\left(6\right)\right\}\cdot \left(-2\right)`

And of course 16 - 6 = 10, simplifying the expression to " - 2
`*` 10 " leaving us with a solution of - 20.

Answer 2

Explanation:

Following B. O. D. M. A. S rule :

= { [ 8 / 2] ^2 - 6} * (-2)

= { 4 ^ 2 - 6} * - 2

= 10 * - 2

= - 20
