help solve ã18+ã32=

  • math 117 -

    sorry it suppose to say sqrt18 +sqrt 32=

  • math 117 -

    According to my calculator, the square root of 18 = 4.2426 and the square root of 32 = 5.6569

  • math 117 -

    It probably says simplify, not "solve"
    √18 + √32
    = √9√2 + √16√2
    = 3√2 + 4√2 = 7√2

    Scott,
    If you post expressions involving mathematical symbols, it is best to switch the encoding to Western ISO-8859-1 which is available under "view/character encoding (on Firefox) or "view/Encoding" under Internet Explorer (Western European).

    This way, you can take advantage of all the math symbols available.
