Use the grouping symbols to interpret the following equation: x/8=3^(x+4)/2 . Which expression in the equation represents a product?

2

x/8

3 (x+4)

3(x+4)/2

1 answer

In the equation \( \frac{x}{8} = \frac{3^{(x+4)}}{2} \), we can analyze each of the provided expressions to determine which one represents a product.

  1. \( \frac{x}{8} \): This is a fraction, not a product.
  2. \( \frac{x}{8} \): This is repeated, still a fraction.
  3. \( 3(x+4) \): This expression contains a multiplication of 3 and the sum \( (x+4) \). Thus, it represents a product.
  4. \( \frac{3(x+4)}{2} \): This is a fraction, but it also involves multiplication of 3 and \( (x+4) \) in the numerator, which means it represents a product as well.

Among these expressions, \( 3(x+4) \) explicitly highlights the multiplication of 3 and \( (x+4) \). So the expression that primarily represents a product is

\( 3(x+4) \).
