Q. Write the following expression without negative exponents and without parentheses.\newline(2x)3 (-2 x)^{-3} \newlineAnswer:
  1. Understand Negative Exponents: First, we need to understand the properties of negative exponents. The negative exponent indicates that we should take the reciprocal of the base. So, (2x)3(-2x)^{-3} means we should take the reciprocal of (2x)(-2x) and then raise it to the power of 33.
  2. Reciprocal and Cubing: Taking the reciprocal of (2x)(-2x) gives us 12x\frac{1}{-2x}. Now we need to raise this to the power of 33, which means we will cube both the numerator and the denominator.
  3. Simplify the Expression: Cubing the numerator 131^3 gives us 11. Cubing the denominator (2x)3(-2x)^3 gives us 8x3-8x^3 because (2)3(-2)^3 is 8-8 and (x)3(x)^3 is x3x^3.
  4. Simplify the Expression: Cubing the numerator 131^3 gives us 11. Cubing the denominator (2x)3(-2x)^3 gives us 8x3-8x^3 because (2)3(-2)^3 is 8-8 and (x)3(x)^3 is x3x^3.Putting it all together, we have 13/(2x)31^3 / (-2x)^3 which simplifies to 1/8x31 / -8x^3. Since we typically don't leave negative signs in the denominator, we can write this as 1100.
