Equation at the end of step 3 : 27 4 • —————— 16x6y8 Step 4 :Final result : 27 ————— 4x6y8
The simplified expression is [tex]27/(16x^6y^8).[/tex]
We have,
To simplify the expression [tex]4(3x^2y^4)^3 / (2x^3y^5)^4,[/tex] we can simplify each part separately and then divide.
Let's simplify the numerator first:
[tex](3x^2y^4)^3 = 3^3 * (x^2)^3 * (y^4)^3 = 27x^6y^{12}[/tex]
Now, let's simplify the denominator:
[tex](2x^3y^5)^4 = 2^4 * (x^3)^4 * (y^5)^4 = 16x^{12}y^{20}[/tex]
Now we can divide the numerator by the denominator:
[tex](27x^6y^{12}) / (16x^{12}y^{20})[/tex]
To divide the variables with the same base, we subtract their exponents:
[tex]27/16 * x^{6-12} * y^{12-20}[/tex]
Simplifying further:
[tex]27/16 * x^{-6} * y^{-8}[/tex]
To make the exponents positive, we can move the variables with negative exponents to the denominator:
[tex]27/(16x^6y^8)[/tex]
Therefore,
The simplified expression is [tex]27/(16x^6y^8).[/tex]

Green is with C, Blue is with A, Orange is with D, Purple is with B
Step-by-step explanation:
Hi!
So, it's been a while since I've done math like this, so the way I solved this was simply by doing the equations themselves and seeing which one matches. I'm sure there is an algebraic way to find which ones match, but this is all I know how to do :)
(By the way...I got the decimals by doing the fraction itself. 1 divided by 4(1/4th)=.25, as an example)
1(left)-7/1/4 is the same as 7/ .25. This is 28.
2(left) 2/3/ 4/5 is the same as .6666666/ .8. This is .83333repeating
3(left) 4/5 / 3/2 is the same as .8/1.5. This is .53333repeating
4(left) 1/4 / 1/7 is the same as .25/.143. This is 1.74(approx.)
1(right) 2/3 x 5/4 is the same as .66666 x 1.25 This is .8333 approx.
2(right) 1/4 x 7 is the same as .25*7. This is 1.75
3(right) 7*4 is 28.
4(right) 4/5 x 2/3 is the same as .8x.66666. This is .533
Now, we can match.
Green is with C.
Blue is with A
Orange is with D
Purple is with B
