Q. Express the following fraction in simplest form, only using positive exponents.\newline2(p3b5)23b2 \frac{2\left(p^{-3} b^{5}\right)^{-2}}{3 b^{-2}} \newlineAnswer:
  1. Write Expression, Identify Exponents: Write down the given expression and identify the negative exponents.\newlineThe given expression is (2(p3b5)2)/(3b2)(2(p^{-3}b^{5})^{-2})/(3b^{-2}).\newlineWe need to simplify this expression and express it with only positive exponents.
  2. Apply Negative Exponent Rule: Apply the negative exponent rule, which states that an=1ana^{-n} = \frac{1}{a^n}, to the terms with negative exponents.\newline(2(p3b5)2)/(3b2)(2(p^{-3}b^{5})^{-2})/(3b^{-2}) becomes (2/(p3b5)2)/(3/b2)(2/(p^{3}b^{-5})^2)/(3/b^{2}).
  3. Apply Power Rule: Simplify the expression by applying the power rule, which states that (am)n=amn(a^m)^n = a^{m*n}.2(p3b5)2\frac{2}{(p^{3}b^{-5})^2}/3b2\frac{3}{b^{2}} becomes 2p6b10\frac{2}{p^{6}b^{-10}}/3b2\frac{3}{b^{2}}.
  4. Eliminate Negative Exponents: Multiply the numerator and the denominator by b10b^{10} to eliminate the negative exponent in the denominator.\newline2b10p6b10b103b2\frac{2b^{10}}{p^{6}b^{-10}} \cdot \frac{b^{10}}{3b^{2}} becomes 2b10p6b103b2\frac{2b^{10}}{p^{6}} \cdot \frac{b^{10}}{3b^{2}}.
  5. Cancel Common Terms: Simplify the expression by canceling out the common bb terms and multiplying the numerators and denominators.2b10p6×b103b2\frac{2b^{10}}{p^{6}} \times \frac{b^{10}}{3b^{2}} becomes 2b203p6b2\frac{2b^{20}}{3p^{6}b^{2}}.
  6. Combine B Terms: Simplify the expression by combining the b terms. (2b20)/(3p6b2)(2b^{20})/(3p^{6}b^{2}) becomes (2b18)/(3p6)(2b^{18})/(3p^{6}).
  7. Check for Common Factors: Check for any common factors between the numerator and the denominator that can be simplified.\newlineThere are no common factors between 2b182b^{18} and 3p63p^{6}, so the expression is already in its simplest form.
