## anonymous one year ago Given the function f(x)=5x3/2: Calculate exactly the value(s) of x when f(x)=6. If there is more than one such value, enter all possible values as a comma separated list of (exact) values.

|dw:1442547333380:dw| Is that right?

2. anonymous

no it's 5(x)^(3/2)

3. dinamix

$6 = x ^{\frac{ 3 }{ 2 }} = \sqrt{x}^{3}$

4. dinamix

@Theanitrix look i make it easy

5. dinamix

$\sqrt[3]{6}=\sqrt{x}$ $(\sqrt[3]{6})^{2}=x$

6. dinamix

@Theanitrix i hope u understand how i do it

7. anonymous

i understand , so x= 3.30?

8. dinamix

ops i miss 5 ok i fix my answer$(\sqrt[3]{\frac{ 6 }{ 5}})^{2}=x$

9. dinamix

the same steps just i miss 5 okey

10. dinamix

x=1.29

11. dinamix

12. anonymous

so no other possible values?

13. dinamix

yup
