If 3^19[x+i y]=[(3)/(2)+(√(3))/(2) i] and x=k y, then k equals (a) (1)/(√(3)) (b) √(3) (c) (-1)/

step 1 So in the given question we are given that if 3 raised to the power, if 3 raised to the power 49

If 3^19[x+i y]=[(3)/(2)+(√(3))/(2) i] and x=k y, then k...

Key Concepts

Ratio of Real to Imaginary Components

Determining the ratio between the real and imaginary components involves comparing the coefficients of these parts in a complex number. This concept is useful when the problem establishes a relationship between the two components, enabling the calculation of one variable in terms of another.

Polar Form and Euler's Formula

Polar form represents a complex number in terms of its magnitude and angle, using expressions like re^(i?) or r(cos? + i sin?). Euler's formula provides a connection between the polar and rectangular forms, simplifying operations such as multiplication and exponentiation in the context of complex numbers.

Equating Real and Imaginary Parts

When two complex numbers are equal, their real parts must be equal and their imaginary parts must be equal as well. This principle is fundamental when solving equations involving complex numbers, as it allows one to set up separate equations to solve for unknown variables.

Complex Numbers

Complex numbers are elements of the form a + bi, where 'a' is the real part and 'b' is the imaginary part (with i being the square root of -1). They extend the real number system and are crucial in many areas of mathematics for solving equations that have no real solutions.

Rectangular Form Representation

The rectangular form of a complex number expresses it as a sum of its real part and its imaginary part. This form is particularly useful when comparing or equating complex numbers, as it allows one to directly match the coefficients of the real and imaginary components.
