To simplify the expression (\frac{3^{-4} \cdot 2^3 \cdot 3^2}{2^4 \cdot 3^n}), first combine the powers of 3 in the numerator: (3^{-4 + 2} = 3^{-2}). The expression becomes (\frac{3^{-2} \cdot 2^3}{2^4 \cdot 3^n}). Next, simplify the powers of 2: (\frac{2^3}{2^4} = 2^{-1}). Thus, the simplified expression is (\frac{2^{-1} \cdot 3^{-2}}{3^n} = \frac{2^{-1}}{3^{n+2}}).
21 over 40 is irreducible as a fraction expression. 21 over 40 is 0.525 as a decimal expression.
21 over 72, or 7 over 24 (simplified)
It is an algebraic expression that can be simplified to: 4.5a-2.5
It is: 1/13

D.2√3
1 divided by 25 multiplied by z to the third power
The numerator and denominator can be simplified becuase any unit over itself is equal to 1. So for example meter/meter = 1.
(7/6)(1/2) = (7/12) your answer is 7/12
9 over 13 NO! 9/7 * 9/6 = 9/7 * 3/2 = 27/14 which can be simplified to 113/14 At the second stage 9/6 was simplified to 3/2 using the common factor 3.
It is: 12/5 times 5/8 = 60/40 = 3/2 simplified or as 1.5
