Question

Find the lcd of the pair of expressions

2/7x^10y^4 * 2/14x^8 y^ 7
I think the answer is, 14x^18 y^11

Answer 1

`(2)/(7) {x}^(10) {y}^(4) \: and \: (2)/(14) {x}^(8) {y}^(7) \\ lcd = 14 {x}^(10) {y}^(7)`
Answer is

`14 {x}^(10) {y}^(7)`

When it's powered numbers, remember to choose the one with the largest power. For example,

`{x}^(10)`
And

`{x}^(8)`
Choose 10, same goes to y, where you choose 7 not 4 since 7 is larger.

Hope this helps. - M
