Evaluate the Expression: Simplifying (b×9×a)⁶

To expand the expression $\left(b \times 9 \times a\right)^6$, we'll apply the power of a product rule for exponents, which states that $(xyz)^n = x^n \times y^n \times z^n$.

• Step 1: Identify each factor within the base: $b$, $9$, and $a$.
• Step 2: Apply the exponent to each factor individually:
• $b^6$
• $9^6$
• $a^6$

By multiplying these results together, the expanded form is $b^6 \times 9^6 \times a^6$.

Therefore, the correct expression is $b^6 \times 9^6 \times a^6$.
