Answer 1

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

A. 7 b cubed c
B. 12 b cubed c squared
C. 35 b cubed c squared
D. Start Fraction a minus b + 2 over a b c cubed End Fraction

Answer 2

#1.
LCD(1/2, 4/x^2) = 2x^2

#2.
LCD(8/(5b) , 12/(7b^3 c)) = 35b^3 c

I suspect a typo

Answer 3

D. x squared

Answer 4

B. 12 b cubed c squared

Answer 5

Thank you for catching that. Yes, you are correct that there was a typo in the first problem. The correct LCD for 1/2 and 4/x^2 is indeed 2x^2.
