(3.4 × 10²) × (2 × 10³)
? × 10

Explanation:

Step1: Group coefficients and powers

$(3.4 \times 2) \times (10^2 \times 10^3)$

Step2: Multiply the coefficients

$3.4 \times 2 = 6.8$

Step3: Multiply the powers of 10

$10^2 \times 10^3 = 10^{2+3} = 10^5$

Step4: Combine the results

$6.8 \times 10^5$

Answer:

$6.8 \times 10^5$
