Question 268639
((8b^(3))/(7)*t^(2))*((49t^(5))/(64)*b)

Multiply (8b^(3))/(7) by t^(2) to get (8b^(3)t^(2))/(7).
((8b^(3)t^(2))/(7))*((49t^(5))/(64)*b)

Multiply (49t^(5))/(64) by b to get (49bt^(5))/(64).
((8b^(3)t^(2))/(7))*((49bt^(5))/(64))

Multiply (8b^(3)t^(2))/(7) by (49bt^(5))/(64) to get (7b^(4)t^(7))/(8).
((7b^(4)t^(7))/(8))

Remove the parentheses around the expression (7b^(4)t^(7))/(8).
Answer: (7b^(4)t^(7))/(8)
