-13 * -13 = 169 13 * 13 = 169

  • anonymous
Okay, well... \[x^2=-169\] That NEGATIVE sign pretty much gives it away.

@love_jessika15 you are wrong -13^2 = 169

anonymous

its just stupid pre algebra. thats nothing to fight about. i just want to know the right answer. it doesent matter who gives it
anonymous
  • anonymous
oh and show your work :D
phi
  • phi
x^2 means x*x if you say x is -13 then x*x means -13 * -13 and that is +169 there is *no way* to square a real number and get a negative result some day you will learn about imaginary numbers. But for now, *no way*
anonymous
  • anonymous
so a?
Michele_Laino
  • Michele_Laino
namely, the equation: \[\Large {x^2} = - 169\] has no real solutions
Michele_Laino
  • Michele_Laino
yes!
phi
  • phi
yes, choice a) undefined
