The equivalent expressions using only positive exponents are 1/(7x⁵y⁸)⁵ and (5y³/x⁶)⁵
<h3>How to simplify the expressions?</h3>
<u>Expression 1</u>
From the question, the expression is given as
(49x¹⁰y¹⁶)⁻⁵/²
Express the radicals as roots
So, we have
(49x¹⁰y¹⁶)⁻⁵/² = √[(49x¹⁰y¹⁶)]⁻⁵
Take the square root of each of the factor in the bracket
This gives
(49x¹⁰y¹⁶)⁻⁵/² = (7x⁵y⁸)⁻⁵
Apply the negative exponent rule of indices
So, we have
(49x¹⁰y¹⁶)⁻⁵/² = 1/(7x⁵y⁸)⁵
<u>Expression 2</u>
From the question, the expression is given as
(125x⁻¹⁸y⁹)⁵/₃
Express the radicals as roots
So, we have
(125x⁻¹⁸y⁹)⁵/₃ = ∛[(125x⁻¹⁸y⁹)]⁵
Take the cube root of each of the factor in the bracket
This gives
(125x⁻¹⁸y⁹)⁵/₃ = (5x⁻⁶y³)⁵
Apply the negative exponent rule of indices
So, we have
(125x⁻¹⁸y⁹)⁵/₃ = (5y³/x⁶)⁵
Hence, the equivalent expression is (125x⁻¹⁸y⁹)⁵/₃ = (5y³/x⁶)⁵
