Question

How do you evaluate `[4( 8- 4) \div 2] ^ { 2} + 4`?

Answer 1

See a solution process below:

Explanation:

First, execute the Subtraction within the parenthesis"

`[4(color(red)(8) - color(red)(4)) -: 2]^2 + 4 =>`

`[4 xx 4 -: 2]^2 + 4`

Next, execute the Multiplication and Division within the brackets going from left to right:

`[color(red)(4) xx color(red)(4) -: 2]^2 + 4 =>`

`[color(red)(16) -: color(red)(2)]^2 + 4 =>`

`8^2 + 4`

Then, execute the Exponent operation:

`color(red)(8^2) + 4 =>`

`64 + 4`

Now, execute the Addition operation:

`64 + 4 =>`

`68`
