Given z1 = 1+i and z2 = 2+3i.
a. let w = z1 ⋅ z2. find w and the multiplicative inverse of w.
b. show that the multiplicative inverse of w is the same as the product of the multiplicative inverses of z1 and z2.

(a)

Multiplicative inverse of w will be

(B) As w is same as the product of

So there multiplicative inverse will also be same

Step-by-step explanation:

We have given two complex numbers

and

(a) First we have to find

So

As we know that

So

Multiplicative inverse :

It is that number when multiply with the number which we have have to find the multiplicative inverse gives result as 1

So multiplicative inverse of w will be

Because when we multiply with it gives result as 1

(b) As w is same as the product of

So there multiplicative inverse will also be same

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !
