Question

find LCM...10b^4c^9, 2b^6c^8, 15b^7c^6

Answer 1

ok im confused on how to write the problem out. The way I did it was \[2\times5.b.b.b.b.b.b.b.b.b.b.b.b.b\]

Answer 2

the way i did it was what two numbers equal 10 (2x5) then i thought we write out how many b's or c's there are

Answer 3

Forget what I wrote previously.

Answer 4

Instead, think of trying to find the Least Common Denominator

Answer 5

i did that with each number

Answer 6

\[\frac{1}{10b^4c^9}+\frac{1}{2b^6c^8}+\frac{1}{15b^7c^6}\]

Imagine you had to add those up. How would you find the LCD?

Answer 7

would that be 2?

Answer 8

30b^7c^9 is the correct answer here.

Answer 9

ok i have no clue how you got that lol

Answer 10
