Q. Express the following fraction in simplest form, only using positive exponents.3b−22(p−3b5)−2Answer:
Write Expression, Identify Exponents: Write down the given expression and identify the negative exponents.The given expression is (2(p−3b5)−2)/(3b−2).We need to simplify this expression and express it with only positive exponents.
Apply Negative Exponent Rule: Apply the negative exponent rule, which states that a−n=an1, to the terms with negative exponents.(2(p−3b5)−2)/(3b−2) becomes (2/(p3b−5)2)/(3/b2).
Apply Power Rule: Simplify the expression by applying the power rule, which states that (am)n=am∗n.(p3b−5)22/b23 becomes p6b−102/b23.
Eliminate Negative Exponents: Multiply the numerator and the denominator by b10 to eliminate the negative exponent in the denominator.p6b−102b10⋅3b2b10 becomes p62b10⋅3b2b10.
Cancel Common Terms: Simplify the expression by canceling out the common b terms and multiplying the numerators and denominators.p62b10×3b2b10 becomes 3p6b22b20.
Combine B Terms: Simplify the expression by combining the b terms. (2b20)/(3p6b2) becomes (2b18)/(3p6).
Check for Common Factors: Check for any common factors between the numerator and the denominator that can be simplified.There are no common factors between 2b18 and 3p6, so the expression is already in its simplest form.
