Explanation:

Step 1: Define

`a=(5x^2)/(2)`

`b=(2x^2(x-5))/(10x)`

x = 10

Step 2: Evaluate

a

1. Substitute in x:
   `a=(5(10)^2)/(2)`
2. Exponents:
   `a=(5(100))/(2)`
3. Multiply:
   `a=(500)/(2)`
4. Divide:
   `a=250`

b

1. Substitute in x:
   `b=(2(10)^2(10-5))/(10(10))`
2. Exponents:
   `b=(2(100)(10-5))/(10(10))`
3. Subtract:
   `b=(2(100)(5))/(10(10))`
4. Multiply:
   `b=(1000)/(100)`
5. Divide:
   `b=10`
