Solve for y y=2x^3 , x=3

$y = 2 x^{3}$ , $x = 3$

Step 1

Replace all occurrences of $x$ in $y = 2 x^{3}$ with $3$ .

$y = 2 {(3)}^{3}$

$x = 3$

Step 2

Simplify the right side.

Simplify $2 {(3)}^{3}$ .

Raise $3$ to the power of $3$ .

$y = 2 \cdot 27$

$x = 3$

Multiply $2$ by $27$ .

$y = 54$

$x = 3$

$y = 54$

$x = 3$

$y = 54$

$x = 3$
