Question

Find the LCD of the pair of expressions.

Start Fraction 8 over 5 b End Fraction; Start Fraction 12 over 7 b-cubed c End Fraction

Answer 1

The LCD (Least Common Denominator) of the pair of expressions can be found by determining the prime factors of the denominators.

For the first expression: 5 = 5
For the second expression: 7 = 7

Therefore, the LCD of the pair of expressions is 5*7 = 35.
