    Radical Equations and Inequalities.

    hello i have been absent due to illness and i dont know how to do this worksheet besides a few problems.
    4.) v1/3 +1 = 0
    5.) 18 - 3y^1/2 = 25
    6.)3 on the square root of 2w = 4
    9.) 3 on the square root of 3r-6 = 3
    12.) (2d+3)^1/3 =2
    13.) (t-3)^1/3 =2
    14.) 4-(1-7u)^1/3 =0
    15.) The square root of 3z -2 = the square root of z-4
    16.) The square root of g+1 = the square root of 2g-7
    17.) The square root of x-1 = 4 the square root of x+1
    18.) 5+ the square root of s-3 is less than or equal to 6
    19.) -2+ the square root of 3x+3 is less than 7
    20.) - the square root of 2a+4 is greater than or equal to -6
    21.) 2 the square root of 4r-3 is greater than 10
    22.) 4- the square root of 3x+1 is greater than 3
    23.) the square root of y+4 (end square root) -3 is greater than or equal to 3
    24.) -3 the square root of 11r +3 is greater than -15

    any help would be very much appreciated. Thanks.

    Sorry, but this is an unreasonable number of posted problems. Please note that this is not a teaching website ... the idea here at MHF is for you to show some work so folks who offer help can guide you to a correct solution.

    I recommend you do a web search for radical equations and inequalities and see if you can learn something from the many examples provided. You also need to see your instructor for help after any lengthy absence.
