Step-by-Step Solution

To solve this problem, we need to express (23×5×7)x\left(\frac{2}{3 \times 5 \times 7}\right)^x by applying the rule for powers of a fraction.

Using the exponent rule (ab)x=axbx\left(\frac{a}{b}\right)^x = \frac{a^x}{b^x}, we proceed as follows:

  • Step 1: Express the numerator and denominator with the exponent xx.
    The expression (23×5×7)x\left(\frac{2}{3 \times 5 \times 7}\right)^x becomes 2x(3×5×7)x\frac{2^x}{(3 \times 5 \times 7)^x}.
  • Step 2: Apply the power of a product rule to the denominator.
    This results in (3×5×7)x=3x×5x×7x(3 \times 5 \times 7)^x = 3^x \times 5^x \times 7^x.
  • Step 3: Substitute back into the fraction from Step 1.
    We get 2x3x×5x×7x\frac{2^x}{3^x \times 5^x \times 7^x}.

Therefore, the original expression (23×5×7)x\left(\frac{2}{3 \times 5 \times 7}\right)^x simplifies to 2x3x×5x×7x\frac{2^x}{3^x \times 5^x \times 7^x}.

The correct answer is: 2x3x×5x×7x \frac{2^x}{3^x \times 5^x \times 7^x} .

Answer

2x3x×5x×7x \frac{2^x}{3^x\times5^x\times7^x}
