The equivalent expression for the given expression is 4² or 16.
The given expression is [tex]\frac{-4^{4} }{-4^{2}}[/tex].
We need to write the equivalent expression for the given expression.
Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value for the variable.
Now, [tex]\frac{-4^{4} }{-4^{2}}[/tex] can be simplified as follows:
=[tex]4^{4} \times4^{-2} =4^{4-2}[/tex] (∵[tex]\frac{a^{m} }{a^{n} } =a^{m-n}[/tex])
=4²=16
Therefore, the equivalent expression for the given expression is 4² or 16.
