Question

(-3+5)^2-3,4^2/(-3)+5+3,4

Answer 1

(-3+5)^2-3,4^2/(-3)+5+3,4=2^2-(17:5)^2/-3+5+3.4=4-(289:25)/5.4=-189/25/27/5=-7/5=-1.4

Answer 2

Let's simplify the expression step by step:

1. (-3 + 5)^2 - 3: First, simplify the parentheses: (-3 + 5) = 2 Now, we have 2^2 - 3 2^2 = 4, so the expression becomes 4 - 3 = 1

2. 4^2 / (-3) + 5 + 3.4: First, calculate 4^2 = 16 Now, divide 16 by -3: 16 / -3 ≈ -5.33333333333 (rounded to 11 decimal places) Finally, add 5 and 3.4 to the result: -5.33333333333 + 5 + 3.4 ≈ 3.06666666667 (rounded to 11 decimal places)

So, the final simplified expression is: 1 - 3.06666666667 ≈ -2.06666666667 (rounded to 11 decimal places)
