The correct Answer is:
To find the number of terms in the expansion of \((x - 2)^3\) raised to the power of 3, we can follow these steps: ### Step 1: Simplify the expression We start with the expression \([(x - 2)^3]^3\). According to the laws of exponents, we can multiply the exponents: \[ [(x - 2)^3]^3 = (x - 2)^{3 \cdot 3} = (x - 2)^9 \] ### Step 2: Identify the form of the binomial expansion The expression \((x - 2)^9\) is a binomial expression of the form \((a + b)^n\), where \(a = x\), \(b = -2\), and \(n = 9\). ### Step 3: Use the formula for the number of terms in a binomial expansion The number of terms in the expansion of \((a + b)^n\) is given by the formula: \[ \text{Number of terms} = n + 1 \] ### Step 4: Apply the formula In our case, \(n = 9\). Therefore, the number of terms in the expansion of \((x - 2)^9\) is: \[ 9 + 1 = 10 \] ### Final Answer Thus, the number of terms in the expansion of \([(x - 2)^3]^3\) is **10**. ---
