7/8 Because there are (7 marbles that are not 8 / 8 possibilities).
Write 12.54 as 12.54/1. Multiply both numerator and denominator by 10 for every number after the decimal point
<span>12.54 × 100/1 × 100</span><span> = </span><span>1254/100. </span>Reducing the fraction gives

the answer is a
Step-by-step explanation:
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
Any number but 0 is compatible because you can add any number to 428.
