    c.

    sqrt ( 4 ) + sqrt ( 9 ) = 2 + 3 = 5

    2 .)

    b.

    sqrt ( 36 ) * sqrt ( 49 ) = 6 * 7 = 43

    3 .)

    sq root of - 66 = sqrt ( - 1 ) * sqrt ( 66 ) = i * 8.124

    approx. 8 i

    Remarq ( i ) = sqrt ( - 1 )

    4 .)

    sqrt ( 3 ) = 1.732

    1. 7 round to the nearest tenth
