    1) √169 - 8² -√225 + 9²
    = 13 - 64 + 15 + 81 = -51 + 96 = 45

    2) √256 + 7² - √144 + 13²
    = 16 + 49 - 12 + 169 = 65 - 181 = 246

    3) √625 - 8² - √225 + 9²
    = 25 - 64 - 15 + 81 = (-39) - 15 + 81
    = (-39) + (-15) + 81 = -54 + 81 = 27

    4) √729 - 10² - √121 + 8²
    = 27 - 100 - 11 + 64 = -73 - 11 + 64
    = -73 + (-11) + 64 = -84 + 64 = -20

    5) 13² - √64 - 3² - √225
    = 169 - 8 - 9 - 15 = 152 - 15 = 37

    6) 14² + √49 - 5² + √625
    = 196 + 7 - 25 + 25 = 203 - 25 + 25 = 178 + 25 = 203


    Semoga membantu..........
