    6. Determine order and degree (if defined) of differential equations:
    straight y apostrophe plus 5 space straight y equals 0

    The given differential equation is
    y' + 5 y = 0
    The highest order derivative present in the given differential equation is y' and index of its highest power is one.
    ∴    the given differential equation is of order 1 and degree 1.
