Answer:
The expression that is equivalent to [(2a⁻³b⁴)²/(3a⁵b)⁻²]⁻¹ is; 1/(36a⁴b¹⁰)
The given expression is [(2a⁻³b⁴)²/(3a⁵b)⁻²]⁻¹. By simplifying the terms and applying the laws of indices, we can find that the equivalent expression is 1/(36a⁴b¹⁰).
Explanation:Firstly, we rewrite the equation as [(2a⁻³b⁴)² × (3a⁵b)²]⁻¹.
We simplify (2a⁻³b⁴)² to get 4b⁸/a⁶, and (3a⁵b)² to get 9a¹⁰b².
After simplification, we have [(4b⁸/a⁶) × 9a¹⁰b²]⁻¹.
Using the laws of indices, we simplify a¹⁰/a⁶ to get a⁴, and b⁸ × b² to get b¹⁰.
Finally, [(4b⁸/a⁶) × 9a¹⁰b²]⁻¹ simplifies to (36a⁴b¹⁰)⁻¹, which equals 1/(36a⁴b¹⁰).
