Q. Express the following fraction in simplest form using only positive exponents.3(w3)53w9Answer:
Write & Identify Properties: Write down the given expression and identify the properties of exponents that can be applied.Given expression: (3w9)/(3(w3)5)We can apply the power of a power property for the denominator, which states that (am)n=am∗n.
Apply Power of Power: Apply the power of a power property to the denominator.(3(w3)5)=3×w3×5=3×w15
Rewrite with Simplified Denominator: Rewrite the original expression with the simplified denominator.(3w9)/(3(w3)5)=(3w9)/(3⋅w15)
Simplify by Canceling Factors: Simplify the expression by canceling out common factors in the numerator and the denominator.The common factor of 3 in the numerator and denominator can be canceled out, and we can use the quotient of powers property for the w terms, which states that am/an=am−n when a=0.(3w9)/(3⋅w15)=w9−15=w−6
Rewrite with Positive Exponents: Since we need the expression with only positive exponents, we rewrite w−6 using the property a−n=an1.w−6=w61
