Will mark brainliest, 60 points

Dominik [7]

Answer:

$\boxed{ \bold{ \sf{ \: 1. \: \: \: \: \: 198}}}$

$\boxed{ \bold{ \sf{2. \: \: \: \: \: - 8}}}$

$\boxed{ \bold{ \sf{ 3. \: \: \: \: \: \frac{64}{343} }}}$

Step-by-step explanation:

1. Given, u = 20 , x = 4 , y = 7 , z = 10

$\sf{ \frac{u}{z} + x {y}^{2} }$

⇒ $\sf{ \frac{20}{10} + 4 \times {7}^{2} }$

⇒ $\sf{ \frac{20}{10} + 4 \times 49}$

⇒ $\sf{ \frac{20}{10} + 196}$

⇒ $\sf{ \frac{20 + 196 \times 10}{10} }$

⇒ $\sf{ \frac{20 + 1960}{10} }$

⇒ $\sf{ \frac{1980}{10} }$

⇒ $\sf{198}$

2. $\sf{4( - 2)}$

Multiplying or dividing a positive integer by any negative integer gives a negative integer

= - 8

3. $\sf{( \frac{4}{7} ) ^{3} }$

⇒ $\sf{( \frac{ {4}^{3} }{ {7}^{3} } })$

⇒ $\sf{ \frac{4 \times 4 \times 4 }{7 \times 7 \times 7}}$

⇒ $\sf{ \frac{64}{343} }$

Hope I helped!

Best regards! :D
