Math Problem Statement

Find the values of the real numbers π‘₯ and 𝑦 if: (3𝑦 βˆ’ 2)𝑖¹⁢ + (5 βˆ’ 2π‘₯)𝑖 = 0

Solution

We are given the equation:

(3yβˆ’2)i16+(5βˆ’2x)i=0(3y - 2)i^{16} + (5 - 2x)i = 0

Here, ii is the imaginary unit, which satisfies i2=βˆ’1i^2 = -1. We need to find the real values of xx and yy.

Step 1: Simplify Powers of ii

First, let's simplify the powers of ii:

  • i16i^{16}: Powers of ii cycle every four terms: i1=ii^1 = i, i2=βˆ’1i^2 = -1, i3=βˆ’ii^3 = -i, and i4=1i^4 = 1. Since 1616 is a multiple of 4, i16=1i^{16} = 1.

Thus, the equation becomes: (3yβˆ’2)β‹…1+(5βˆ’2x)i=0(3y - 2) \cdot 1 + (5 - 2x)i = 0 Simplifying further: 3yβˆ’2+(5βˆ’2x)i=03y - 2 + (5 - 2x)i = 0

Step 2: Set Up Real and Imaginary Parts

For this equation to be true, both the real part and the imaginary part must equal zero.

  • Real part: 3yβˆ’2=03y - 2 = 0
  • Imaginary part: 5βˆ’2x=05 - 2x = 0

Step 3: Solve for xx and yy

  1. Solving for yy: 3yβˆ’2=0β‡’3y=2β‡’y=233y - 2 = 0 \quad \Rightarrow \quad 3y = 2 \quad \Rightarrow \quad y = \frac{2}{3}

  2. Solving for xx: 5βˆ’2x=0β‡’2x=5β‡’x=525 - 2x = 0 \quad \Rightarrow \quad 2x = 5 \quad \Rightarrow \quad x = \frac{5}{2}

Final Answer

The real values of xx and yy are: x=52,y=23x = \frac{5}{2}, \quad y = \frac{2}{3}
