Answer:
[tex]\dfrac{s^8t^4}{r^{12}}[/tex]
Step-by-step explanation:
Let as assume that the given expression is
[tex](r^{-3}s^2t)^4[/tex]
We need to find the simplify the given expression.
Using the distributive power property of exponent we get
[tex](r^{-3})^4\cdot (s^2)^4\cdot (t)^4[/tex] [tex][\because (ab)^m=a^mb^m][/tex]
Using rules of exponents we get
[tex]r^{-3\times 4}\cdot s^{2\times 4} \cdot t^4[/tex] [tex][\because (a^m)^n=a^{mn}][/tex]
[tex]r^{-12}\cdot s^{8} \cdot t^4[/tex]
[tex]\frac{s^{8} \cdot t^4}{r^{12}}[/tex]
[tex]\frac{s^{8}t^4}{r^{12}}[/tex]
Therefore, the simplified form of the given expression is [tex]\dfrac{s^8t^4}{r^{12}}[/tex].
