# How do you simplify 3a^2 + 43^2 using PEMDAS given a=2, b=3, c=4?

Jul 18, 2017

$1861$

#### Explanation:

There are only two terms in this expression.

A value should be obtained for each term separately and then the answers can be added in the last step.

Within each term, the normal order of operations applies:
- Brackets (does not apply in this case)
- Powers and roots
- Multiplication and division

$\text{ "color(blue)(3a^2)color(red)( +43^2)" } \left(a = 2\right)$

$= \textcolor{b l u e}{3 {\left(2\right)}^{2}} \textcolor{red}{+ 1849}$

$= \textcolor{b l u e}{3 \left(4\right)} \textcolor{red}{+ 1849}$

$= \textcolor{b l u e}{12} \textcolor{red}{+ 1849}$

$= 1861$
