Question
Which key combination is often used to permanently
delete a file (bypassing Recycle Bin)?Solution
The Shift + Delete removes a file permanently without moving it to the Recycle Bin.
I. x=  √(20+ √(20+ √(20+ √(20…………….∞)) ) )Â
II. y= √(5√(5√(5√(5……….∞)) ) )Â
...I. x2 + 13x + 42 = 0
II. y² + 13y + 40 = 0
I). p2 + 22p + 72 = 0,
II). q2 - 24q + 128 = 0
I. p²= ∛1331
II. 2q² - 21q + 55 = 0
I. 27x6-152x3+125=0
II. 216y6Â -91y3+8=0
I. √(17x) + √51 = 0  Â
II. √(4y) + 3 = 0
I. x2 - 5x - 14 = 0
II. y2 - 16y + 64 = 0
Solve the quadratic equations and determine the relation between x and y:
Equation 1: 6x² - 24x + 18 = 0
Equation 2: 5y² - 20y + 15 = 0
I. 63x² + 146x + 80 = 0
II. 42y² + 109y + 70 = 0
I. x² - 33x + 270 = 0
II. y² - 41y + 414 = 0
