The correct Answer is:
To evaluate \((-3/4)^5\), follow these steps: ### Step 1: Write the expression in expanded form The expression \((-3/4)^5\) means multiplying \(-3/4\) by itself 5 times. Therefore, we can write it as: \[ (-3/4) \times (-3/4) \times (-3/4) \times (-3/4) \times (-3/4) \] ### Step 2: Separate the numerators and denominators We can separate the multiplication of the numerators and the denominators: \[ = \frac{(-3) \times (-3) \times (-3) \times (-3) \times (-3)}{4 \times 4 \times 4 \times 4 \times 4} \] ### Step 3: Calculate the numerator Now, calculate the numerator: \[ (-3) \times (-3) \times (-3) \times (-3) \times (-3) = (-3)^5 \] Calculating \((-3)^5\): \[ (-3) \times (-3) = 9 \\ 9 \times (-3) = -27 \\ -27 \times (-3) = 81 \\ 81 \times (-3) = -243 \] So, \((-3)^5 = -243\). ### Step 4: Calculate the denominator Now, calculate the denominator: \[ 4 \times 4 \times 4 \times 4 \times 4 = 4^5 \] Calculating \(4^5\): \[ 4 \times 4 = 16 \\ 16 \times 4 = 64 \\ 64 \times 4 = 256 \\ 256 \times 4 = 1024 \] So, \(4^5 = 1024\). ### Step 5: Combine the results Now, we can combine the results from the numerator and denominator: \[ (-3/4)^5 = \frac{-243}{1024} \] ### Final Answer Thus, the evaluated result of \((-3/4)^5\) is: \[ \frac{-243}{1024} \] ---
