Which expression is equivalent to 15a^8b^4/5a^4b

LekaFEV [45]

Answer: The given expression $\frac{15a^8b^4}{5a^4b}$ simplified to $3a^4b^3$

Step-by-step explanation:

Given : expression $\frac{15a^8b^4}{5a^4b}$

We have to simplify the given expression $\frac{15a^8b^4}{5a^4b}$

Consider the given expression $\frac{15a^8b^4}{5a^4b}$

Divide the numbers $\frac{15}{5}=3$

$=\frac{3a^8b^4}{a^4b}$

Apply exponent rule, $\frac{x^a}{x^b}\:=\:x^{a-b}$

We have,

$\frac{a^8}{a^4}=a^{8-4}=a^4$

$=\frac{3a^4b^4}{b}$

Cancel out common factor b,

We have

$=3a^4b^3$

Thus, the given expression $\frac{15a^8b^4}{5a^4b}$ simplified to $3a^4b^3$

Answer:

Hello,

Step-by-step explanation:

The well-known magic square. (first apparition in China).

Here it the methode du Marquis de Liouville: (odd square:3,5,7,9,11,13,...)

We are going to put successively the number from 1 to n² (here n=3)

We imagine that the square is put on a sphere;

We begin in the middle of the last line where we put 1

ICI:

We move in direction SE of one case and put le next number

until we reach of multiple of n

After have reached a multiple of n, we move verticaly of one case

and we go to ICI until we reach n²
