$3x ^{1/2} + 5x ^{1/4} -2 = 0$

2. anonymous

Hello!

3. anonymous

Oops thats wrong

4. anonymous

$x = \frac{ 1 }{ 81 }$

5. anonymous

There you go!

6. anonymous

Medal :)?

7. anonymous

I know the answer, but need to know how to get to it

8. anonymous

*facepalm* you should have told me that! XD

9. anonymous

Lol sorry

Let's solve your equation step-by-step. 3x1 2 + 5x1 4 −2=0 Step 1: Simplify both sides of the equation. 3x1 2 + 5x1 4 −2=0 Simplify: (Show steps) 11 4 x−2=0 Step 2: Add 2 to both sides. 11 4 x−2+2=0+2 11 4 x=2 Step 3: Multiply both sides by 4/11. ( 4 11 )*( 11 4 x)=( 4 11 )*(2) x= 8 11 Answer: x= 8 11

solve for m then remember this is x^1/4 and solve for x

Okay, I did all of that and didn't get 1/81.

18. triciaal

what are your values for my m?

19. anonymous

1 and -2

20. triciaal

the graph shows 0.333 which is 1/3 and -2 then the -2 is thrown out I guess because cannot have the square root of a negative

21. anonymous

Why is it m^4?

22. triciaal

23. triciaal

yes
