## Which property of multiplication is shown below? if x = a + bi and y = c + di, x × y = y × x. commutative property identity property

The option A. is correct

Step-by-step explanation:

x = a + bi and y = c + di

Now, x × y = (a + bi) × (c + di)

= ac + adi + bci + bdi²

= ac – bd + i(ad + bc)

Now, y × x = (c+ di) × (a + bi)

= ac + bci + adi + bdi²

= ac – bd + i(ad + bc)

Therefore, x × y = y × x

And if ab = ba then the property is known as commutative property.

Hence, The option A. is correct

AP Calculus AB Multiple Choice 2008 Exam Part B (videos, questions…) – I need to find the number of digits of very large multiplications (about 300 digits each). You can bound the number of digits as follows: floor(log x)*floor(log y) <= digits(x*y) <= ceil(log x)*ceil(log y) log base 10. – davin Jul 3 '11 at 23:30.Multiplication of any real numbers has the associative property: (a x b) x c = a x (b x c). In fact each complex number, z, can be represented as z = x +iy where x and y are real numbers and i is the imaginary square root of -1.Thus the set of complex numbers is the Cartesian product of two sets of…if x = a + bi and y = c + di, x × y = y × x. commutative property identity property distributive property associative property. Thus, commutative property of multiplication is as shown above. According to commutative property of multiplication , for two elements x and y , we have .

If x= 2 and y = 3, what is 2 x y? – Quora – Which property of multiplication is shown below? commutative property. Donte simplified the expression below. mc024-1.jpg. What mistake did Donte make? He did not apply the distributive property correctly for 4(1 + 3i).If x = a + bi and y = c + di, x × y = y × x. commutative property identity property distributive property associative property. Answer: The option A. is correct. Step-by-step explanation: x = a + bi and y = c + di.An exponent (such as the 2 in x2 ) says how many times to use the variable in a multiplication. x3 y z2x y2 z2 = xxx y zzx yy zz = x xx y zz x y y zz = xxy = x2y.
