Can someone solve these for me. much would be appreciated.

37.  sqrt 196 x^4 y^6

= 14x^2y^3

38.    =  8(2x^4 - x^2 + 2) / (x + 4)(x + 2)

Simplify:

sqrt 196x^4y^6   >   14x^4y^6

Steps:

sqrt 196x^4y^6

sqrt 196   =    14

Answer   >    14x^4y^6

Simplify:

16x^4   -    8x^2     +    16 / (x   +   4 ) (x      +     2 )

16x^5    +   64x^4     −    8x^3    −   32x^2    +    16x    +    32 /   x     +   4   =  0

Factor:

8(2x^5     +    8x^4   −   x^3   − 4x^2    +   2x   +   4) / x   +  4   =  0

Hope that helps                              : )
