Well Dear Lakeisha ;

( 27x / 9 ) ( x^8 / 3x^5 )

Step 1
27x / 9
{ 27/ 9 = 3 }
3 * x = 3x

Step 2
( x^8 / 3x^5)
rewrite this like that
1/3 ( x ^ 8 / x ^ 5 )
{ as you know if " x ^ a / x ^ b = x ^ ( a - b) " }
1/3 ( x ^ (8 - 5)) = 1/3 * ( x^3 ) = ( x^3 / 3 )

Step 3
(3x) ( x^3 / 3 ) { simplify ' 3 ' }
so we have ;
x * ( x ^ 3 )
{ as you know if " (x^a) * (x^ b) = x^ (a+b) " }
x * ( x ^ 3 ) = x^ ( 1+3) = x^4

The Total Result is ;
( 27x / 9 ) * ( x^8 / 3x^5 ) = x ^ 4

Good Luck Dear.

Assuming that "x" between the 9 and the x^8 is a multiplication sign, and you mean ((27x)/9)*((x^8)/(3x^5))...

We can rearrange the first term as (27/9)*x, which is equal to 3x

3x * ((x^8)/(3x^5))
Because dividing powers with equal bases is equivalent to subtracting the exponents, we can rearrange that second term as
(x^(8-5))/3 = (x^3)/3
and plug that back in, and go from there:
3x * (x^3)/3
(3*x*x^3) / 3
x* x^3
x^4

I'll assume you mean (27x/9) * (x^8 / (3x^5)). You really should use parentheses to make it clearer, though.

27x/9 reduces to 3x.

For x^8 / (3x^5), use a^x/a^y = a^(x-y) and get x^3/3.

Multiply the two: 3x * x^3 /3 = x^4.

x^4.

(27x/9 x x^8/3x^5=27x/9 * x^8/3x^5)

LET US SEPERATE TWO PARTS:
27x/9 , x^8/3x^5

27x/9 =9*3*x/9
=3x

x^8/3x^5
=x^(8-5)/3
=x^3 / 3

27x/9 * x^8/3x^5
=3x*x^3 / 3
=x^(3+1)
=x^4

-6(x-6) = 2x - 36 the 1st step: do away with the brackets = -6x + 36 = 2x -36 Step 2: separate the x values from the numerical values upload 36 to the two edge -6x + 36 +36 = 2x -36 +36 = -6x + 72 = 2x upload 6x to the two edge -6x + 6x +72 =2x + 6x 72 = 8x Step 3 Dived the two sides by using the x fee 72 / 8 = 8x / 8 9 = x the respond is X = 9

if these are 2 separet equations then
27x/9x=3
x^8/3x^5=x^3/3

3x*(x^3/3)=x^4
