= 2^2 x 3^3 x 2^-5 x 3^-2 x 2^2 

= 4 x 27 x  0.03125 x 0.11 x 4 

= 6

Explanation

Let's consider the radius is r and therefore the Area will be πr².

Now the radius is increased by 4 times than the Area would be.

π(4r)² or the area would work to 16 times (4²=16).

Explanation

a - b = 3

a2 + b2 = 2

the formula used: (a-b)2 = a2 +b2 -2ab

Calculation:

a - b = 3

squaring both sides 

a2 + b2 - 2ab = 9 

2 - 2ab = 9

2 - 9 - 2ab = 0 

-7/2 = ab

To solve this problem, let's assign values to the given symbols and evaluate the expression step-by-step:

- P donates "-" (subtraction)

- Q donates "+"

- R donates "x" (multiplication)

- W donates "+"

Now, let's substitute the symbols with their corresponding operations in the expression:

48 Q 12 R 10 P 8 W 4

= 48 + 12 x 10 - 2 + 8 + 4

Using the order of operations (PEMDAS/BODMAS), we perform the multiplication first:

= 48 + 12 x 10 - 2 + 8 + 4

= 48 + 120 - 2 + 8 + 4

Then, we perform the addition and subtraction from left to right:

= 48 + 120 - 2 + 8 + 4

= 168 - 2 + 8 + 4

= 166 + 8 + 4

= 174 + 4

= 178

Therefore, 48 Q 12 R 10 P 8 W 4 equals 178.

Explanation

 Waqas is taller than Rabail, but shorter than Javed.

- Shahid is the shortest.

- Dawood is taller than Shahid, but shorter than Rohil.

From the given information, we can deduce the following height order:

Shahid < Dawood < Rohil

Now, let's combine this with the information about Waqas, Rabail, and Javed:

Waqas > Rabail > Javed

Combining both sets of information, we can determine the overall height order:

Shahid < Dawood < Rohil < Waqas < Rabail < Javed

Therefore, Javed is the tallest among all the mentioned individuals.
