Q.

Jawaban:

limit bentuk (0/0)

lim x –> 7

= (x – 7)/√x – √7

lim x –> 7

= (x – 7)/(√x – √7) x (√x + √7)/(√x + √7)

lim x –> 7

= (x – 7)(√x + √7)/(x – 7)

lim x –> 7

= (√x + √7)

= (√7 + √7)

= 2√7

Jawab:

Penjelasan dengan langkah-langkah:

$lim_{x to 7} ( frac{x - 7)}{sqrt{x} - sqrt{7} } )$

=============================

lim x=> 7 ( x – 7 / √ x – √ 7 )

( x – 7 / √ x – √7)

( 7 – 7 / √ 7 – √ 7 )

( 0 / √ 0 )

0 / 0
