  sqrt(45)+ sqrt(20)+ sqrt(5)-sqrt(125)=??
  I came up with 6sqrt5 I know it's wrong. I think I messed up the breakdown of the sqrt of 125
  
  • algebra -
  
  sqrt(125) = sqrt (5*25) = 5 sqrt(5)
  
  • algebra -
  
  sqrt(9*5) + sqrt(4*5) + sqrt5 - sqrt(25*5)
  = (3 +2 +1 -5)sqrt5 = sqrt5

  So is the answer 6sqrt(5)?? Thank you
  
  • algebra -
  
  sqrt (9*5)+sqrt(4*5)+sqrt(5) -5 sqrt(5)
  
  3 sqrt(5) +2 sqrt (5) + 1 sqrt(5) - 5 sqrt (5)
  
  that is
  1 sqrt(5)

  ohhh I see what I did wrong Thanks you 2

  No, it is NOT 6 sqrt(5)

  sqrt 6 * sqrt 8 also sqrt 7 * sqrt 5 6.92820323 and 5.916079783 So you can see the steps — sqrt 6 * sqrt 8 = sqrt 48 sqrt 7 * sqrt 5 = sqrt 35 I hope this helps a little more. Thanks for asking.

  Please look at my work below: Solve the initial-value problem. y'' + 4y' + 6y = 0 , y(0) = 2 , y'(0) = 4 r^2+4r+6=0, r=(16 +/- Sqrt(4^2-4(1)(6)))/2(1) r=(16 +/- Sqrt(-8)) r=8 +/- Sqrt(2)*i, alpha=8, Beta=Sqrt(2) y(0)=2, e^(8*0)*(c1*cos(0)+c2*sin(0))=c2=2 …

  Solve the initial-value problem. Am I using the wrong value for beta here, 2sqrt(2) or am I making a mistake somewhere else?
  9. ### Calculus
  
  Evaluate the indefinite integral: 8x-x^2. I got this but I the homework system says its wrong:sqrt((-x-8)x)/(2*sqrt(x-8)*sqrt(x))*(((sqrt(x-8)*(x-4)*sqrt(x))-32*log(sqrt(x-8)+sqrt(x))

  Evaluate sqrt7x (sqrt x-7 sqrt7) Show your work. sqrt(7)*sqrt(x)-sqrt(7)*7*sqrt(7) sqrt(7*x)-7*sqrt(7*7) sqrt(7x)-7*sqrt(7^2) x*sqrt 7x-49*x ^^^ would this be my final answer?
