How do I answer this.?

Question

-2^2 + I2-10I

I was thinking 4+8. Or would it be 4+ 12?

Answer 1

-2^2 + I2-10I

-2^2 =4

I2-10I = |-8| = 8

so 4+ 8 = 12

Answer 2

If you mean (-2)^2 +|2-10| then yes the answer is 4+8. You work out the value inside the modulus first and then (possibly) change its sign as you had to here.

Answer 3

it's 4 + 8

Answer 4

it will be 12

because

its

-2^2 + I2-10I

4+8=12

Answer 5

4+8

every step within the absolute value is normal

and converted to positive at the END

Answer 6

4 + 8

12
