Answer:

4 is the real part

2i is the imaginary part

Step-by-step explanation:

In complex number a+ib

'a' is the real part and ib is the imaginary part

All complex numbers comes with real part and imaginary part

The number without 'i' is always a real part

the term that has 'i' is an imaginary part

In the given complex number, 4+2i

4 is the real part

2i is the imaginary part

Evaluate the expression.

Gemiola [76]

Answer:

98 is the answer of the expression

Step-by-step explanation:

AS it is a simple algebraic expression so these are solved by BDMAS rule which means that we have to solve the brackets first starting from the smaller bracket first which is inside a larger bracket then we will move to Division then multiplication then addition and then subtraction

so the following equation can be written as

= $2^{3}[\frac{1}{4}+4(36/12)]$

First of all solving smallest bracket and division inside it

= $2^{3}[\frac{1}{4}+4(3)]$

Multplying 4 inside

= $2^{3}[\frac{1}{4}+12]$

Now solving the 2³

= $8[\frac{1}{4}+12]$

Now solving the expression inside the bracket by taking LCM

= $8[\frac{1 + 4*12}{4}]$

= $8[\frac{1 + 48}{4}]$

= $8[\frac{49}{4}]$

Now multiplying 8 with inside values

= $[\frac{8*49}{4}]$

AS 8 cuts out with 4 so

= 2 * 49

= 98

which is the answer of the expression

I would say D because if you do 10 x 2 you get 20 then minus 9 equals 11 and that seems around the right measurements
