Someone who is brave enough please do it I cannot understand a thing in this sum given by sir.

Answer:
x=2
y=8
Step-by-step explanation:
hope it's useful
That's simple! Always remember this formula for doing such sums: x¹/y¹=x²/y²
Now let's solve this.
So, here
x¹=4 x²=9
y¹=16 y²=a (As the value is unknown, you can assign any variable to it. So here I am assigning 'a')
Now, applying formula:
x¹/y¹ = x²/y²
4/16 = 9/a (simplify)
1/4 = 9/a (transpose)
1×a = 9×4
a = 36
So, our first blank got filled! Now let's go a bit faster. But always remember the x¹ and y¹ change as the x² and y² change.
x¹=9 x²=a (now here the value of x is unknown so the variable would be assigned here)
y¹=36 y²=48
Now, applying formula:
x¹/y¹ = x²/y²
9/36 = a/48
1/4 = a/48
1×48 = a×4 (We can skip this step)
48 = 4a
4a = 48
a = 48/4
a = 12
So let's move on to third.
x¹=12 x²=a
y¹=48 y²=36
Now, applying formula:
x¹/y¹ = x²/y²
12/48 = a/36
1/4 = a/36
36 = 4a
4a = 36
a = 36/4
a = 9
Next one...
x¹=9 x²=3
y¹=36 y²=a
Now, applying formula:
x¹/y¹ = x²/y²
9/36 = 3/a
1/4 = 3/a
a = 4×3
a = 12
So, we're on the last one now!
x¹=3 x²=a
y¹=12 y²=4
Now, applying formula:
x¹/y¹ = x²/y²
3/12 = a/4
1/4 = a/4
4 = 4a
4a = 4
a = 4/4
a = 1
and if you need it, the real value of x=1 and y=4.
So we completed all the sums!
i hv attached the completed table for help.
i hope you would have learnt it by now and this will help u.
please mark me as brainliest and give a thanks.
