The book I have does not explain in very good detail how to do this. I need to find all 4 roots. How I tried to do it was by setting it equal to x. Then I made x^4=-7+24I .

(1) Write 7 − 24 i in trigonometric form. (This looks like r (cos θ + i sin θ) and is shortened to r c i s θ.)

Now putting the value of b in equation 1 we get. a^2 - (12/a)^2 = 7 => a^2 -(144/a^2) = 7 => a^4 -144 = 7a^2 => a^4 -144 = 7a^2 => a^4 - 7 a^2 -144 = 0. Solving above quadratic equation we get. a^2 = (7+√(576+49))/2 or (-7+24I)^(1/4) .

and solving simultaneously by sub b=12/a gives a^2 - 144/a^2=7, a^4-7a^2 -144=0 giving (a^2-16)(a^2+9)=0 so a^2=16 (must be +) giving. a=4, b=3 or a=-4,b= -3 so z^2=4+3i or z^2= -4-3i. Do the same with z^2, z=c+id z^2=(c^2-d^2)+2icd=4+3i so => a^2 -b^2 + 2(a)(b)i =7 + 24i. Comparing both sides we get two equations a^2 - b^2 =7. And 2ab = 24 => ab = 12 => b =12/a. Now putting the value of b in equation 1 we get.

Θ = arctan[(-24)/(-7)] = arctan(24/7) + π = 1.410π rad = 254° The real part is -7 [24]7.ai (full company name [24]7.ai, Inc.) is a customer experience software and services company based in California that uses artificial intelligence and machine learning to understand consumer intent.

∴ 7 + 24i = (a 2 – b 2) + 2abi[∵ i 2 = – 1] Equating real and imaginary parts, we get a 2 – b 2 = 7 and 2ab = 24 ∴ a 2 – b 2 = 7 and b = `12/"a"` ∴ `"a"^2 - (12/"a")^2` = 7 ∴ `"a"^2 - 144/"a"^2` = 7 ∴ a 4 – 144 = 7a 2 ∴ a 4 – 7a 2 – 144 = 0 ∴ (a 2 – 16)(a 2 + 9) = 0 ∴ a 2 = 16 or a 2 = – 9 But a ∈ R ∴ a 2 ≠ – 9 ∴ a 2 = 16 ∴ a = ± 4 When a = 4, b = `12/4` = 3. When a = – 4, b = `12/(-4)` = – 3 ∴ `sqrt(7 + 24"i")` = ± (4 + 3i ∴ 7+ 24i = (x 2 – y 2) + 2xyi[∵ i 2 = – 1] Equating the real and imaginary parts separately, we get, x 2 – y 2 = 7 and 2xy = 24 ∴ y = `12/x` ∴ `x^2 - (12/x)^2` = 7 ∴ `x^2 - 144/x^2` = 7 ∴ x 4 – 144 = 7x 2 ∴ x 4 – 7x 2 – 144 = 0 ∴ (x 2 – 16)(x 2 + 9) = 0 ∴ x 2 = 16 or x 2 = – 9. Now x is a real number ∴ x 2 ≠ – 9 ∴ x 2 = 16 ∴ x = ± 4. When x = 4, y = `12/4` = 3. When x = – 4, y = `12/(-4)` = – 3 ∴ the square roots of 7 + 24i are 4 + 3i Let the square root of 7 + 24i = a +bi where a and b are real numbers. We know that i^2 = -1 Now (a+bi)^2 = 7 + 24i => a^2 -b^2 + 2(a)(b)i =7 + 24i Comparing both sides we get two equations a^2 - b^2 =7 And 2ab = 24 => ab = 12 => b =12/a Now putti Click here👆to get an answer to your question ️ Find the square root of the following complex numbers 7 + 24i.
