In this case x = 4.001 {\displaystyle x=4.001} , so 4.001 {\displaystyle {\sqrt {4.001}}} is approximately 2 + 4.001 − 4 4 = 2.00025 {\displaystyle 2+{\frac {4.001-4}{4}}=2.00025} .
وفي هذه الحالة x = 4.001 {\displaystyle {\mathcal {}}x=4.001} ، إذاً 4.001 {\displaystyle {\sqrt {4.001}}} يساوي تقريباً 2 + 4.001 − 4 4 = 2.00025 {\displaystyle 2+{\frac {4.001-4}{4}}=2.00025} .
