Answer 1

It’s so blurry sorry

Answer 2

$\large\bf\green{<u>Question</u>:-}$

$solve \: this$

$\frac{49 \times {z}^{ - 3} }{ {7}^{ - 3} \times 10 \times {z}^{ - 5} }$

___________________________

$\large\bf\blue{Solution:-}$

$\frac{49 \times {z}^{ - 3} }{ {7}^{ - 3} \times 10 \times {z}^{ - 5} }$

$= > \frac{49 \times {z}^{ 2} }{ {7}^{ - 3} \times 10 }$

$= > \frac{ {7}^{2} \times {z}^{ 2} }{ {7}^{ - 3} \times 10 }$

$= > \frac{ {7}^{5} \times {z}^{ 2} }{ 10 }$

$= > \frac{16807 {z}^{2} }{10}$
