First, pull out the GCM from the two terms: 3x^6(x^3-64)
Then factor the remains using the difference of cubes: 3x^6(x-4)(x^2+4x+16)
It is simply would be: √π
= √3.14
= 1.7728
In short, Your Answer would be: 1.7728
Hope this helps!
4.4
Not sure if I'm right but I think it's 4.4. If I'm wrong I'm sorry, if someone can tell me if ik right that would be great. <3
Your answer in standard form would be 5+31i
