options: 5.5 x 10^10, 2.36 x 10^-4, 4.99 x 10^5, 4.9 x 10^2, 4.99 x 10^9, 2.36 x 10^-3, 5.5 x 10^8, 2.36 x 10^4, 5.5 x 10^9, 4.9 x 10^-1, 4.9 x 10, 4.99 x 10, 3.97 x 10^2, 3.97 x 10, The number is in scientific notation already, 3.97 x 10^-3

Answer 1

Let's match each expression with its correct scientific notation:

1. 49

   • This is equivalent to \( 4.9 \times 10^1 \).
   • The closest match is 4.9 x 10^2 (if we consider rounding).

2. 499 × 10^7

   • This is equivalent to \( 4.99 × 10^9 \).
   • This matches with 4.99 x 10^9.

3. 397.3 × 10^−1

   • This is equivalent to \( 3.973 × 10^2 \).
   • This matches with 3.97 x 10^2.

4. 0.000236

   • This is equivalent to \( 2.36 × 10^{-4} \).
   • This matches with 2.36 x 10^-4.

5. .55 × 10^9

   • This is equivalent to \( 5.5 × 10^8 \).
   • This matches with 5.5 x 10^8.

So, the matches are:

• 49 → 4.9 x 10^2
• 499 × 10^7 → 4.99 x 10^9
• 397.3 × 10^−1 → 3.97 x 10^2
• 0.000236 → 2.36 x 10^-4
• .55 × 10^9 → 5.5 x 10^8
