Q. What is the expression for f(x) when we rewrite(321)x⋅(21)9x−5 as (21)f(x)f(x)=□
Simplify given expression: We need to express the given function in the form of ((21)f(x)). To do this, we will first simplify the given expression using the properties of exponents.The given expression is ((321)x⋅(21)9x−5).We know that (321) can be written as (21)5 because 25=32.So, ((321)x) can be rewritten as ((21)5)x.Using the property of exponents (am)n=am⋅n, we get ((21)5⋅x).Now, the expression becomes ((21)5⋅x⋅(21)9x−5).
Combine exponents: Next, we will combine the exponents of the same base using the property am×an=am+n. So, we combine the exponents of (1/2) by adding them together: 5x+(9x−5). This simplifies to 5x+9x−5. Combining like terms, we get 14x−5. Therefore, the expression can now be written as (1/2)14x−5.
Express as a single power: We have now expressed the original expression as a single power of (21). This means that f(x)=14x−5.
