The LCM of 28 and 42 is 84. Since y2 and x2 are multiples of y and x respectively, they are automatically the LCM. That makes the answer 84x2y2
The LCM of 8 and 34 is 136, which is the multiple of the highest power of prime factors from both numbers (23 x 17 = 2 x 2 x 2 x 17 = 136).
The LCM of 4 and 5 is 20, which is the multiple of the highest power of prime factors from both numbers (22 x 5 = 2 x 2 x 5 = 20).
-2
The LCM is 6b2c3
Assuming you mean 2b^-6, with the 2b not in parenthesis, it simplifies to 2/b6, or 2 over b to the sixth.
-2b + 7 -3b = 2 -2b +7 -3b +2b = 2 + 2b 7 -3b + 3b = 2 + 2b +3b 7-2 = 2-2 + 2b + 3b 5 = 5b 1 = b
The Least Common Multiple (LCM) for 2 6 7 is 42.

The question is somewhat ambiguous: the answers are LCM[3T2, 5T] =15T2 or LCM[(3T)2, 5T] =45T2
8b + 11 - 3b = 2b + 2 5b + 11 = 2b + 2 5b - 2b = 2 - 11 3b = -9 b = -3
a = 2b - c a + c = 2b (a+c)/2 = b b = (a+c)/2
4b^2
5 over 2 thats the answer
