What method would you use to square the value 3 + √-1 ? In what other cases would you use this method? Explain.

galina1969 [7]

Answer:

1) the types of number are the negative integers (e.g √-1 √-3 √-5 are not defined)

2) the answer is No, proof: 2x√-1 is not defined because √-1 doesn't exist

3) the answer is No, proof: √-1 - 3 is not defined because √-1 doesn't exist

4) the answer is Yes, proof: (√-1 )²= -1 this is a real number

5) the answer is No, proof: (√-1 )^3= (√-1 )²(√-1 )= - 1(√-1 ), and - 1(√-1 ) is not defined because √-1 doesn't exist

6) the result would be defined with the following cases:

√-1+n, n>1

√-1xn, n<0

√-1/n, n<0

7) the result would not be defined with the following cases:

√-1+n, n<0

√-1xn, n>0

√-1/n, n>0

8) to square 3 + √-1, I use the method of complex number

i²= -1, it implies i= √-1

so 3+√-1=3+i, and then (3+√-1)²=(3+i)²= 9 -1+6i= 8-i= 8-√-1

9) it is used for finding complex roots of a number

Solve 4x- c = k for x. <br>A. x = k-c/4<br>B. x = 4(k-c)<br>C. x- k+c/4<br>D. x = 4 (k+c)

Harrizon [31]

Answer:

Step-by-step explanation:

You would first add c to the side that k is on and then divide k+c by 4 because it is 4x which means they are being multiplied together so you have to divide to get them apart.

Solve each equation below for x show all work and check your answer by substituting it back into the equation and verifying that

Viefleur [7K]

Answer:

The equations are

(a) x/3 = 6

(b) (5x + 9)/2 = 12

(d) 5/x = 20/8

The answers to the question are

(a) x = 18

(b) x = 3

(d) x = 2

Step-by-step explanation:

(a) x/3 = 6

Therefore x = 3×6 = 18

x =18

Substituting the value of x in the above equation, we have

18/6 = 3 verified

(b) (5x + 9)/2 = 12

Multiplying both sides by 2 gives

(5x + 9)/2 × 2 = 12×2 = 24

5x + 9 = 24 or x = (24-9)/5 = 3

Substituting the value of x in the above equation, we have

(5×3 + 9)/2 = 24/2 = 12 verified

x = 3

Multiplying both sides by 4, we have

x/4×4 = 9/6×4 = 6

x = 6

Substituting the value of x in the above equation, we have

(6/4 = 9/6 = 3/2 verified

(d) 5/x = 20/8

Inverting both equations, we have

x/5 = 8/20

Multiplying both sides by 20 we have x/5 × 20 = 8/20 × 20 or 4x = 8 and x = 2

Substituting the value of x in the original equation, we have

2/5 = 2/5 = 8/20 verified

x = 2
