find the product of 9 by 2 X ^ 2 Y and (X + 2 Y )verify the result for X equal to 1 by 2 and Y equal to 3
Answers
Answer:
In the above formula for multiplication, if v is zero, then you get a formula for multiplying a complex number x + yi and a real number u together:
(x + yi) u = xu + yu i.
In other words, you just multiply both parts of the complex number by the real number. For example, 2 times 3 + i is just 6 + 2i. Geometrically, when you double a complex number, just double the distance from the origin, 0. Similarly, when you multiply a complex number z by 1/2, the result will be half way between 0 and z. You can think of multiplication by 2 as a transformation which stretches the complex plane C by a factor of 2 away from 0; and multiplication by 1/2 as a transformation which squeezes C toward 0.
Answer:
9/2x³y+ 9/2x²y²
Step-by-step explanation:
=9/2x²y (x+2y)
=according to question :
=9/2x²y×x + 9/2x²y×2y
=9/2x³y+ 9/2x²y²
verify the question?
x = 1/2 and y =3
