Q. easy!

$displaystylelim_{ x rightarrow 5 } left (8x times {2}^{x} + {4x}^{2} right)$

$= 8(5) times {2}^{5} + 4( {5}^{2} )$

$small{ = 40 times ( underline{2 times 2} times underline{2 times 2} times 2) + 4(5 times 5)}$

$= 40 times ( underline{4 times 4} times 2) + 4(25)$

$= 40 times (16 times 2) + 100$

$= 40 times 32 + 100$

$= 1.280 + 100$

$= 1.380$

Penjelasan dengan langkah-langkah:

$Lim (8x : times 2 {}^{x} + 4x {}^{2} ) \ x = 5 \ = 8(5) times 2 {}^{5} + 4(5) {}^{2} \ = 40 times 32 + 100 \ = 1.280 + 100 \ = 1.380$
