What is the smallest value of x for which the radical expression (radical sign)2x-10 is a real number

  • algebra 2 -

    Usually, the radical sign defaults to mean the squres root. So, the question is for what values of x is the square root of (2x-10) a real number. The square root is real for all non-negative values. So, for what values of x will (2x-10) be non-negative? What is the smallest value?
