Math Problem Statement

Work out the value of \( \frac{2^9 \times 2^{-2}}{2^4} \)

Solution

We are tasked with solving the following expression:

29×2224\frac{2^9 \times 2^{-2}}{2^4}

Step-by-Step Solution:

  1. Combine the exponents in the numerator: 29×22=29+(2)=272^9 \times 2^{-2} = 2^{9 + (-2)} = 2^{7} This simplifies the expression to: 2724\frac{2^7}{2^4}

  2. Simplify the fraction using the properties of exponents (i.e., subtract the exponents when dividing like bases): 2724=274=23\frac{2^7}{2^4} = 2^{7 - 4} = 2^3

  3. Calculate the value of 232^3: 23=82^3 = 8

Final Answer:

8\boxed{8}
