I have attached the problem in a picture below!​
lesantik [10]

Answer:

A. The solution set is x = 5 or -7

Step-by-step explanation:

\sqrt[4]{ {x}^{2} + 2x }  =  \sqrt[4]{35}  \\ {({x}^{2} + 2x) }^{ \frac{1}{4} }  =  {(35)}^{ \frac{1}{4} }  \\ {x}^{ \frac{1}{2} } + {2x}^{ \frac{1}{4} }   =  {35}^{ \frac{1}{4} }  \\   {x}^{2}  + 2x = 35 \\  {x}^{2}  + 2x  -  35 = 0 \\ (x - 5)(x + 7) = 0 \\ x = 5  \: or \:  - 7

Therefore, the answer is A. as the solution is x = 5 or -7

Find the error (-8x^2y^2)^2= -64x^4y^4
ExtremeBDS [4]

Answer:

(-8)^2\neq-64

Step-by-step explanation:

Using the distributive property to expand, we have

(-8x^2y^2)^2=(-8)^2(x^2)^2(y^2)^2.

Squaring each term, we have

(-8x^2y^2)^2=64x^4y^4.

The mistake was that 8^2=64, not -64. Using the fact that 8^2=64, the right answer would be

\boxed{64x^4y^4}.
