It looks like I'm still here after all... It's like this, see \[\Large \frac{\sqrt x}{5}=2\]

Yes thats what it looks like but I dont know how to solve for x though

Yeah, well, that's why I'm here :) multiplying both sides by 5 will cancel the denominator on the left, right?
anonymous
  • anonymous
Im not sure.. I dont know how to do this :/
terenzreignz
  • terenzreignz
Okay, keep calm and carry on ;) \[\Large 5 \times \frac{\sqrt x}{5}= 2 \times 5\] right?

There has to be an answer for x that will = 2
terenzreignz
  • terenzreignz
Yeah, cool it :) I just multiplied both sides by 5... basic Multiplication property of equality; if two sides are equal, multiplying both sides of the equation by the same number would not affect the equality...

  • anonymous
Okay thank you :D
terenzreignz
  • terenzreignz
So, 5 cancels out at the left... \[\large \cancel 5 \times \frac{\sqrt x}{\cancel 5}= 10\] \[\Large \sqrt x = 10\] can you do it from here?
anonymous
  • anonymous
Yes thank you
terenzreignz
  • terenzreignz
Okay, good :) What's your answer?
anonymous
  • anonymous
Hold on still trying to figure it out
terenzreignz
  • terenzreignz
Squaring cancels out the square root... in that... \[\Large \sqrt{a}^2 = a\]
terenzreignz
  • terenzreignz
So we can square both sides of the equation... \[\Large \sqrt x^2 = 10^2\] we get \[\Large x = 100\] And that's it :) Don't worry, in time, this will be second nature to you :)

Ys I do Ill try using that for when another question pops up like that
