Answer 1

Answer:

• 8.5×10⁵

Step-by-step explanation:

• 2.5×10³ × 3.4×10² =
• (2.5×3.4) × 10³⁺² =
• 8.5×10⁵

Answer 2

$\\ \rm\longmapsto 2.5\times 10^3\times 3.4\times 10^2$

$\boxed{\sf a^m\times a^n=a^{m+n}}$

$\\ \rm\longmapsto 2.5\times 3.4\times 10^3\times 10^2$

$\\ \rm\longmapsto 8.5\times 10^{3+2}$

$\\ \rm\longmapsto 8.5\times 10^5$
