Math Problem Statement

(-10)^2-5(10^3) times (-2)

Solution

Let's break down the expression step by step:

(10)25(103)×(2)(-10)^2 - 5(10^3) \times (-2)

Step 1: Simplify each part of the expression

  1. First term: (10)2(-10)^2

(10)2=100(-10)^2 = 100

  1. Second term: 5(103)×(2)-5(10^3) \times (-2)
  • First calculate 103=100010^3 = 1000.
  • Then, multiply by 5-5: 5×1000=5000-5 \times 1000 = -5000.
  • Now, multiply by 2-2: 5000×(2)=10000-5000 \times (-2) = 10000.

Step 2: Combine the results

10010000=9900100 - 10000 = -9900

Final Answer:

9900\boxed{-9900}
