Translate each of the arithmetic expressions below into Circles of Evaluation, then translate them to Code. Hint: Two useful functions are num-sqr and num-sqrt.

Arithmetic Circle of Evaluation Code

1

( 16 + 3^ 2 ) / ( √49 - 2 )$\displaystyle {{16 + { 3 }^ 2 } \over {\sqrt{ 49 } - 2}}$

2

45 - 9 × ( 3 + ( 2 - 4 ) ) - 7$\displaystyle 45 - 9 \;\times\; ( 3 + ( 2 - 4 ) ) - 7$

3

( 50 ÷ 5 ) × 2 - ( ( 3 + 4 ) × 2 - 5 )$\displaystyle ( 50 \div 5 ) \;\times\; 2 - ( ( 3 + 4 ) \;\times\; 2 - 5 )$
