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

Which rational number equals 0 point 2 with bar over 2? 1 over 10 1 over 9 2 over 10 2 over 9

Alja [10]

Answer:

$0.\bar2=\frac{2}{9}$

Step-by-step explanation:

We want to find the rational number which is equal to $0.\bar2$ .

Let $y=0.\bar2$ ....eqn(1)

Multiply both sides by 10

$10y=2.\bar2$ .....eqn (2)

Subtract eqn (1) from eqn (2)

$10y-y=2.\bar2-0.\bar2$

$\implies 9y=2$

Divide both sides by 9.

$\implies y=\frac{2}{9}$
