​

Answer 1

Answer:

$45y = 5 - 5 \\ 45y = 0$

Answer 2

Given,

$\[{\left( { - 1} \right)^4} \times {\left( { - 1} \right)^{ - 4}}\]$

Solution,

$\[\begin{array}{l} = {\left( { - 1} \right)^4} \times {\left( { - 1} \right)^{ - 4}}\\ = {\left( { - 1} \right)^4} \times \frac{1}{{{{\left( { - 1} \right)}^4}}}\\ = 1\end{array}\]$

Hence the value is 1.
