Step-by-step explanation:

$\tt{( {p}^{10} {r}^{ - 5) ^{ \: \frac{1}{5} } } }$

⟶ $\tt{ {p}^{10 \times \frac{1}{5}} \: {r}^{ - 5 \times \frac{1}{5} } }$

⟶ $\tt{ {p}^{2} \: {r}^{ - 1}}$

⟶ $\tt{ {p}^{2} \cdot \frac{1}{r}}$

⟶ $\boxed{ \tt{ \frac{ {p}^{2} }{r}}}$

$\red{ \boxed{ \boxed{ \tt{Our \: final \: answer : \boxed{ \tt{ \frac{ {p}^{2} }{r}}}}}}}$

Hope I helped ! ♡

Have a wonderful day / night ! ツ

Step-by-step explanation:

Length and breadth is in the ratio 2:3

Then, let length = 2x and breadth = 3x

Area of rectangle = l×b = 2x×3x = 6 $x^{2}$

Now if breadth is increased by 50% ,

our new breadth will be = 3x + 50%(3x)

= 4.5x

And length is increased by same number of units, length = 2x+ 2x = 4x

New area = l×b = 4.5x × 4x

= 18 $x^{2}$

Percentage change in area = $\frac{New area - old area}{old area}$ ×1000

= $\frac{18x^{2}-6x^{2} }{6x^{2} }$ ×100

= 200%
