Write 2x to the power of -2 without negative indices.
How is the answer 2/x squared? Please explain

  • Maths -

    A negative exponent indicates division. Consider

    x^-2 * x^2 = x^0 = 1
    therefore,

    x^-2 = 1/x^2

    In your case,

    2x^-2 = 2/x^2


    A negative exponent in the numerator becomes positive in the denominator, and vice-versa. So,

    x^-2/y^-3 = y^3/x^2
