# What is the value of the expression 2x^3+3y^2-17 when x=3 and y=4?

Nov 22, 2016

The value of the expression is $85$.

#### Explanation:

$2 {x}^{3} + 3 {y}^{2} - 17$

Substituting $x$ with $3$ and $y$ with $4$, we get:

$2 {\left(3\right)}^{3} + 3 {\left(4\right)}^{2} - 17$

$2 \left(27\right) + 3 \left(16\right) - 17$

$54 + 48 - 17$

$85$
