90² + 20²

= (90×90) + (20×20)

= 8.100 + 400

= 8.500

Lim x³ + 2x - 60x

x → 8

》x³ + 2x - 60x

》8³ + 2(8) - 60(8)

》(8×8×8) + 16 - 480

》(64×8) + 16 - 480

》512 + 16 - 480

》528 - 480

》48

Penyelesaian soal :

$\tt {90}^{2} + {20}^{2}$

$\tt = (90 \times 90) + {20}^{2}$

$\tt = 8.100 + {20}^{2}$

$\tt = 8.100 + (20 \times 20)$

$\tt = 8.100 + 400$

$\tt = 8.500$

$\\$

$\sf Lim \: x → 8 \: \: x {}^{3} + 2x - 60x$

$\sf = 8 {}^{3} + 2(8) - 60(8)$

$\sf = 8 {}^{3} +( 2 \times 8) -( 60 \times 8)$

$\sf = 8 {}^{3} +16 -480$

$\sf = 512 +16 -480$

$\sf = 528 -480$

$\sf =48$

$\\$
