4. lim √X²+3x+5 = √1²+3.1+5 = √1+3+5 = √9 = 3
     x⇒1
5. lim ( 3x² + 5x - 2/2x + 1)² = (3.2²+5.2-2/2.2+1)² = (12+10-2/4+1)²
    x⇒2                                 = (20/4)² = (5)² = 25
6. lim X³-x²-x+10/x²+3x+2 = 2³-2²-2+10/2²+3.2+2 = 8-4-2+10/4+6+2
    x⇒2                             = 12/12 = 1
