( { \frac{4 {x}^{3} }{ {y}^{4} }) }^{ - 2}  =  \frac{16x {}^{6} }{ {y}^{8} }

\frac{(4 {x}^{3})^{ - 2}  }{ { {(y}^{4} )}^{ - 2} }  =  \frac{16 {x}^{6} }{ {y}^{8} }

\frac{ {16x}^{ - 6} }{ {y }^{ - 8} }  = \frac{ {16x}^{6} }{ {y}^{8} }

The power of -2 was mistook as 2.

X squared + 12 x + 3 = 7 solve by completing the square
GarryVolchara [31]

ax^2 + bx + c

x^2 + 12x + 3 = 7

x^2 + 12x = 4

Take b, half it, then square it--

x^2 + 12x + 36 = 40

That equation becomes

(x+6)^2 = 40

+ 6 = ± (square root of 40)

= 0.324555

= −12.3246
