Q. Simplify the following expression to simplest form using only positive exponents.\newline(36x6y2)52 \left(36 x^{-6} y^{2}\right)^{-\frac{5}{2}} \newlineAnswer:
  1. Apply Negative Exponent Rule: Apply the negative exponent rule to the entire expression.\newlineThe negative exponent rule states that an=1ana^{-n} = \frac{1}{a^n}. We will apply this rule to the entire expression (36x6y2)52(36x^{-6}y^{2})^{-\frac{5}{2}}.\newline(36x6y2)52=1((36x6y2)52)(36x^{-6}y^{2})^{-\frac{5}{2}} = \frac{1}{((36x^{-6}y^{2})^{\frac{5}{2}})}
  2. Apply Power of Power Rule: Apply the power of a power rule.\newlineThe power of a power rule states that (am)n=amn(a^m)^n = a^{m*n}. We will apply this rule to each part of the expression inside the parentheses.\newline1(3652)(x652)(y252)\frac{1}{(36^{\frac{5}{2}})(x^{-6*\frac{5}{2}})(y^{2*\frac{5}{2}})}
  3. Simplify Exponents: Simplify the exponents.\newlineNow we will simplify the exponents by multiplying them.\newline1(3652)(x15)(y5)\frac{1}{(36^{\frac{5}{2}})(x^{-15})(y^{5})}
  4. Simplify Numerical Part: Simplify the numerical part of the expression. 3636 is a perfect square, so we can simplify 365236^{\frac{5}{2}} by taking the square root of 3636, which is 66, and then raising it to the power of 55. 1(65)(x15)(y5)\frac{1}{(6^5)(x^{-15})(y^5)}
  5. Calculate 656^5: Calculate 656^5. \newline65=6×6×6×6×6=77766^5 = 6 \times 6 \times 6 \times 6 \times 6 = 7776\newline1(7776)(x15)(y5)\frac{1}{(7776)(x^{-15})(y^{5})}
  6. Apply Negative Exponent Rule to x15x^{-15}: Apply the negative exponent rule to x15x^{-15}. The negative exponent rule states that an=1ana^{-n} = \frac{1}{a^n}. We will apply this rule to x15x^{-15}. 1(7776)(1x15)(y5)\frac{1}{(7776)(\frac{1}{x^{15}})(y^{5})}
  7. Combine Terms: Simplify the expression by combining the terms.\newlineNow we combine the terms under the single denominator.\newline1(7776x15y5)\frac{1}{\left(\frac{7776}{x^{15}y^{5}}\right)}
  8. Rewrite with Positive Exponents: Rewrite the expression with positive exponents only.\newlineSince we want only positive exponents, we will move x15x^{15} to the denominator.\newline1(7776)(y5)(x15)\frac{1}{(7776)(y^{5})(x^{15})}
  9. Check for Further Simplifications: Check for any further simplifications.\newlineThere are no further simplifications possible, as 77767776 is already in its simplest form, and there are no like terms to combine with x15x^{15} and y5y^{5}.
