A) 0.00000000305
B) 0.0000000305
C) 305,000,000
D) 30,500,000,000

Answer 1

When multiplying two numbers in scientific notation, you multiply the coefficients and add the exponents. The number equivalent to 3.05E-8 is 0.0000000305.

Step-by-step explanation:

When multiplying two numbers in scientific notation, you multiply the coefficients and add the exponents. In this case, the product of the two numbers given is 3.05E-8. In scientific notation, this can be expressed as 3.05 × 10-8. To determine which number is equivalent to 3.05E-8, we need to look at the coefficient:

1. A) 0.00000000305: This number is equal to 3.05 times 10-9, which is a smaller value than 3.05E-8.
2. B) 0.0000000305: This number is equal to 3.05 times 10-8, which is the same as 3.05E-8. So, B) is equivalent to 3.05E-8.
3. C) 305,000,000: This number is equal to 3.05 times 108, which is a much larger value than 3.05E-8.
4. D) 30,500,000,000: This number is equal to 3.05 times 1010, which is a much larger value than 3.05E-8.

Therefore, the number equivalent to 3.05E-8 is B) 0.0000000305.
