Answer:
The final answer is s⁴t⁴/r⁵
Step-by-step explanation:
Let's simplify the expression r-3s5t2/r2st-2, this way:
1. Variable r:
We have r⁻³/r² = r ⁻³⁻² = r⁻⁵ = 1/r⁵
2. Variable s:
We have s⁵/s = s ⁵⁻¹ = s⁴/1 = s⁴
3. Variable t:
We have t²/t⁻² = t ²⁻⁽⁻²⁾ = t⁴/1 = t⁴
4. Adding the pieces:
We put variables together:
1/r⁵ * s⁴ * t⁴
The final answer is s⁴t⁴/r⁵
