Math Problem Statement

(8 x 10^-3) x (2 x 10^6)

Solution

To solve the expression (8×103)×(2×106)(8 \times 10^{-3}) \times (2 \times 10^6), we can break it into two parts:

  1. Multiply the constants: 8×2=168 \times 2 = 16

  2. Multiply the powers of 10: 103×106=103+6=10310^{-3} \times 10^6 = 10^{-3 + 6} = 10^3

Now, putting everything together: (8×103)×(2×106)=16×103(8 \times 10^{-3}) \times (2 \times 10^6) = 16 \times 10^3

This is the same as: 16,000or1.6×10416,000 \quad \text{or} \quad 1.6 \times 10^4

So, the final result is 16,000 or 1.6×1041.6 \times 10^4.
