NumberForm[{0.073808836682`30,0.794740579742`30},5]

{0.073809,0.794740000000000000000000000000}

Alternatives to making NumberForm listable are

NumberForm[#,5]&/@{0.073808836682`30,0.794740579742`30}

{0.073809,0.79474}

Thread[NumberForm[{0.073808836682`30,0.794740579742`30},5]]

{0.073809,0.79474}
