Question

Radical__?___ divided by 5 = 2. What goes in the radical?

Answer 1

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

Answer 2

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

Answer 3

And thank you for helping me

Answer 4

Yeah, well, that's why I'm here :)
multiplying both sides by 5 will cancel the denominator on the left, right?

Answer 5

Im not sure.. I dont know how to do this :/

Answer 6

Okay, keep calm and carry on ;)
\[\Large 5 \times \frac{\sqrt x}{5}= 2 \times 5\]
right?

Answer 7

There has to be an answer for x that will = 2

Answer 8

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...

Answer 9

Okay thank you :D

Answer 10

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?

Answer 11

Yes thank you

Answer 12

Okay, good :)
What's your answer?

Answer 13

Hold on still trying to figure it out

Answer 14

Squaring cancels out the square root... in that...
\[\Large \sqrt{a}^2 = a\]

Answer 15

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 :)

Answer 16

oh my goodness! i dont understand math

Answer 17

But you understand how I got the answer? :)

Answer 18

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

Answer 19

Sorry, it might have been too quick... a bit crash-course - y

Answer 20

I have to go now, okay? Have fun with Math ^.^
