Use the general formula to find the multiplicative inverse of each complex number.
a. 2 + 3i
b. −7 − 4i
c. −4 + 5i

(a)

(b)

(c)

Step-by-step explanation:

We have the expressions an we have to find the multiplicative inverse

Multiplicative inverse

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

(a) its multiplicative inverse will be

After rationalizing So multiplicative inverse will be  

(b) We have given number

Multiplicative inverse will be

After rationalizing

(c) We have given number

Its multiplicative inverse will be

After rationalizing

So its multiplicative inverse will be

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
