FIND THE LCM OF (2+9U),(4-81U)AND (2-9U)???? HELP

NO.

Just recognize that 4-81u^2 = (2+9u)(2-9u) and that should help

it also helps to
a) proofread you question before submitting it
b) STOP SHOUTING IN ALL CAPS!

To find the Least Common Multiple (LCM) of the given complex numbers (2+9U), (4-81U), and (2-9U), follow these steps:

Step 1: Write each complex number in its standard form.
(2+9U), (4-81U), (2-9U)

Step 2: Determine the factors of each complex number.
For (2+9U):
The factors are 2 and 9U.
For (4-81U):
The factors are 4 and 81U.
For (2-9U):
The factors are 2 and 9U.

Step 3: Find the common factors.
The common factors are 2 and 9U.

Step 4: Calculate the LCM.
Multiply all the common factors together:
LCM = 2 * 9U = 18U.

Therefore, the LCM of (2+9U), (4-81U), and (2-9U) is 18U.
