Answer:

Step-by-step explanation:

Well we know that

$224=2^{5} *7$

so we can get the 2 outside of the radical

$x^{11} =(x^{5} )^{2} *x$

and we can get the x^2 outside too.

$y^8=y^5*y^3$

and we also can get y outside.

so we have:

$2x^{2}y\sqrt[5]{7xy^3}$

If f(x)=x-1/3 and g(x)=3x+1, what is (f o g)(x)?

BlackZzzverrR [31]

Answer:

$3x+\frac{2}{3}$

Step-by-step explanation:

$f(x)=x-\frac{1}{3}$

$g(x)=3x+1$

Hence, $(f o g)(x)=f(3x+1)$

But, $f(3x+1)=(3x+1)-\frac{1}{3}$

Simplifying,

$f(3x+1)=3x+(1-\frac{1}{3})$

= $f(3x+1)=3x+(\frac{3-1}{3})$

= $f(3x+1)=3x+(\frac{2}{3})$

Hence, $(f o g)(x)=3x+(\frac{2}{3})$
