Answer:

  (b)  15 over 56 times a squared

Step-by-step explanation:

You want the product of (5/8a) and (3/7a).

Multiplication

The commutative and associative properties of multiplication help you find this product:

  [tex]\dfrac{5}{8}a\,\times\,\dfrac{3}{7}a = \left(\dfrac{5}{8}\cdot\dfrac{3}{7}\right)\times (a\cdot a)=\dfrac{5\cdot3}{8\cdot7}a^2=\boxed{\dfrac{15}{56}a^2}[/tex]
