Find the least common multiple of these two expressions. 15x^7y^3u^8 and 6y^4u^5

snow_tiger [21]

Answer:

$30x^7y^4u^8$

Step-by-step explanation:

We have been given two expressions $15x^7y^3u^8$ and

$6y^4u^5$

Now we need to find out least common multiple of these two expressions.

First we need to find out what is common factor of both expressions. $15x^7y^3u^8$ and

$6y^4u^5$

Least common multiple means find the expression which can be divided by both expressions.

15 and 6 both goes into 30

so 30 is part of LCM (least common multiple )

Now pickup the highest exponent of each variable.

So we get $x^7y^4u^8$

Hence required least common multiple is $30x^7y^4u^8$

The number 15 is the geometric mean of 25 and what other number?

kvv77 [185]

Answer:

Step-by-step explanation:

$\text{The geometric mean of two numbers}\ a\ \text{and}\ b:\\\\M=\sqrt{(a)(b)}\\\\\text{We have}\\\\M=15,\ a=25\\\\\text{substitute:}\\\\15=\sqrt{25b}\qquad\text{square of both sides}\\\\15^2=(\sqrt{25b})^2\\\\225=25a\qquad\text{divide both sides by 25}\\\\\dfrac{225}{25}=\dfrac{25b}{25}\\\\9=b\to b=9$
