Simplify Absolute Value: We need to simplify the expression inside the square root first. Let's start by simplifying the absolute value expression ∣21+π1∣. Calculate the value inside the absolute value. 21+π1=2π+π1 Since π is approximately 3.14159, which is greater than 2, the numerator (2π+1) is positive. Therefore, the absolute value of a positive number is the number itself. ∣21+π1∣=∣2π+π1∣=2π+π1
Simplify Exponent: Now, let's simplify the exponent (−1)∣21+π1∣.Substitute the absolute value we found into the exponent.(−1)∣21+π1∣=(−1)(2π+1)/πSince the exponent is a rational number and not an integer, the result will be complex. However, the base is −1, and any power of −1 that is not an integer will result in a complex number with a magnitude of 1.
Simplify Term: Next, we need to simplify the term (−π⋅∣21+π1∣+1). Substitute the absolute value we found into the expression. (−π⋅∣21+π1∣+1)=(−π⋅((2π+1)/π)+1) Simplify the expression. =(−π⋅(2π+1)/π+1)=(−(2π+1)+1)=(−2π−1+1)=−2π
Rewrite Original Expression: Now we have the simplified terms, we can rewrite the original expression with these simplified parts. −(−1)(2π+1)/π∗(−2π) Since (−1)(2π+1)/π is a complex number with a magnitude of 1, we can denote it as cis(θ) where cis(θ) represents cos(θ)+isin(θ) and θ is some angle. The negative sign in front of it will change the direction of the angle, but the magnitude will still be 1.
Multiply Complex Number: We can now multiply the complex number cis(θ) by −2π. The multiplication of a complex number with a real number will only affect the magnitude, not the direction (angle). Since the magnitude of cis(θ) is 1, the magnitude of the product will be 2π.
Take Square Root: Finally, we take the square root of the product.−(−1)(2π+1)/π∗(−π/2)=−cis(θ)∗(−π/2)Since the magnitude of cis(θ) is 1, and we are multiplying by −π/2, the magnitude under the square root is π/2. The square root of a negative real number is a complex number. Therefore, the result will be a complex number with a magnitude of π/2.
Express in Terms of i: The final step is to express the complex number in terms of i, the imaginary unit.−2π=i2πThis is because the square root of a negative number is imaginary.
