Answer:
8.75 × 10³
Explanation:
Multiply the coefficients and the exponential terms separately; then multiply them together
2.5 × 3.5 = 8.75.
When you multiply exponential terms, you add the exponents.
10¹⁰ × 10⁻⁷ = 10⁽¹⁰⁻⁷⁾ = 10³
The product is 8.75 × 10³.
A scientific calculator does the operation automatically. The buttons may have different labels on your calculator, but the key sequence is usually something like
2.5 Exp 10 × 8.5 Exp +/- 7 = 8.75×10⁻³
