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

" "color(blue)(3a^2)color(red)( +43^2)" "(a=2)

=color(blue)(3(2)^2)color(red)( +1849)

=color(blue)(3(4))color(red)( +1849)

=color(blue)(12)color(red)( +1849)

=1861
