Full solution

Q. following. Express your answers i\newline(b) 253×(1125)3 \quad \sqrt[3]{25} \times\left(\frac{1}{\sqrt{125}}\right)^{-3}
  1. Simplify Cube Root: We need to simplify the expression 253×(1125)3 \sqrt[3]{25} \times \left(\frac{1}{\sqrt{125}}\right)^{-3} . Let's start by simplifying each part separately.
  2. Simplify Fraction: First, we simplify 253 \sqrt[3]{25} . The cube root of 2525 is not a whole number, but we can leave it in radical form as 253 \sqrt[3]{25} .
  3. Raise to Power: Next, we simplify (1125)3 \left(\frac{1}{\sqrt{125}}\right)^{-3} . We know that 125=53=5 \sqrt{125} = \sqrt{5^3} = 5 , so 1125=15 \frac{1}{\sqrt{125}} = \frac{1}{5} .
  4. Calculate Result: Now, we raise 15 \frac{1}{5} to the power of 3-3, which is the same as taking the reciprocal and raising it to the power of 33: (15)3=53 \left(\frac{1}{5}\right)^{-3} = 5^3 .
  5. Multiply by Cube Root: Calculating 53 5^3 gives us 5×5×5=125 5 \times 5 \times 5 = 125 .
  6. Final Answer: Now we multiply 253 \sqrt[3]{25} by 125125. Since we cannot simplify 253 \sqrt[3]{25} further, the final answer is 125×253 125 \times \sqrt[3]{25} .
