  • anonymous
well the square root has the little 2 on it
Savvy
  • Savvy
wow...!!!!!
anonymous
  • anonymous
what?
Savvy
  • Savvy
you mean its a square of a square root....????
anonymous
  • anonymous

Savvy

is it \[(\sqrt{x+7})^{2}- 10 = -8\]
anonymous

does that help?
Savvy
  • Savvy
lol...no that doesn't help....it still remains the same...that 2 depicts that it is a square root.... the options are wrong for sure.....
anonymous
  • anonymous
well they are on an exam so what do i choose?
Savvy
  • Savvy
don't worry there is something wrong with the question....just be confident and ask your teacher about it....even he/she would agree wid the fact.....even if you are still not satisfied : do you agree that in the given question sqrt.(x+7)=2..????
anonymous
  • anonymous
yes
Savvy
  • Savvy
now try putting all the given values of x in the expression sqrt.(x+7)=2... you'll see that none of them would satisfy the equation....that should be enough for you to agree id the fact dat smthing's wrong wid the question...
