3 0

  -x + y = -13 → -3x + 3y = -39
-4x + 3y = -51 → -4x + 3y = -51
x = 12
-x + y = -13
-(12) + y = -13
-12 + y = -13
+ 12 + 12
  y = -1
   (x, y) = (12, -1)

Exponent Rules: $(b^m)^n = b^{mn}$

Exponent Rules: $\frac{x^m}{x^n} = x^{m-n}$

Step 1: Write expression

$\frac{\sqrt[4]{x^3} }{x^{\frac{1}{12} }}$

Step 2: Rewrite radical

$\frac{{(x^3)^{\frac{1}{4} }} }{x^{\frac{1}{12} }}$

Step 3: Multiply powers (numerator)

$\frac{{x^{\frac{3}{4} }} }{x^{\frac{1}{12} }}$

Step 4: Subtract powers

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