Given :-
To find :-
Solution :-
<u>According</u><u> to</u><u> Question</u><u>,</u>
- x = 3 + √8
- 1/x = 1/3-√8
- 1/x = 1(3+√8)/(3+√8)(3-√8)
- 1/x = 3+√8/3²-(√8)²
- 1/x = 3+√8/9-8
- 1/x = 3 + √8
<u>So </u><u> </u><u>that</u><u> </u><u>,</u>
- x² + 1/x²
- (x + 1/x)² - 2
- ( 3+√8+3-√8)²-2
- 9² - 2
- 81 - 2
- 79
Answer:
w = 6.9
Step-by-step explanation:
6.96 = 2.2(w − 5.1) + 3
6.96 = 2.2w - 11.22 + 3
6.96 = 2.2w - 8.22
collect like term
2.2w = 6.96 + 8.22
2.2w = 15.18
divide through by 2.2
w = 15.18/2.2
w = 6.9
