Verified answer

Answer:

If x = -3.4, then:

|x| = |-3.4| = 3.4

{x} = fractional part of x = 0.4

[x] = greatest integer less than or equal to x = -4

|x|.{x} = 3.4 * 0.4 = 1.36

x[x] = -3.4 * (-4) = 13.6

Therefore, |x|.{x} + x[x] = 1.36 + 13.6 = 14.96.

If \(x = -3.4\), then:

\(|x| \cdot \{x\} + x[x] = 3.4 \cdot \{ -3.4 \} + (-3.4) \cdot (-4) = 3.4 \cdot 0.6 + 13.6 = 2.04 + 13.6 = 15.64.\)
