Answer:

[tex]\huge\boxed{\sf 2.998 \times 10^{10}}[/tex]

Step-by-step explanation:

Given number:

29,980,000,000

Rules:

  • Move the decimal point after the first non-zero digit. (after 2)
  • Here, we will move the decimal point 10 places to the left to move it after the first non-zero digit.
  • Since we move the decimal point 10 places, we will write the number as a multiple of 10¹⁰ (10 being the exponent).

The number will become:

2.998 × 10¹⁰

[tex]\rule[225]{225}{2}[/tex]

Answer:

B. 2.998 x 10¹⁰

Step-by-step explanation:

Given :

  • 29,980,000,000

Steps in solving :

  1. Take the zeros after the last non-zero digit as a power of 10.
  2. Take the non-zero part (in the part) and put a decimal point after between the thousands and hundreds place, and shift the remaining powers of 10 to the previously grouped part.
  3. Adjust further if needed to match an answer.

Solving :

  • 29,980,000,000
  • 2,998 x 10⁷
  • 2.998 x 10³ x 10⁷
  • 2.998 x 10¹⁰
