whats 3.2x10^4 divided by 4.82x10^12? show your work and answer in scientific notation
To divide two numbers in scientific notation, first divide the coefficients and then subtract the exponents of the powers of 10.
(3.2 x 10^4) / (4.82 x 10^12) = (3.2 / 4.82) x (10^4 / 10^12)
Calculating the coefficient: 3.2 / 4.82 ≈ 0.664
Calculating the exponent: 10^4 / 10^12 = 10^(4-12) = 10^(-8)
Therefore, the answer is approximately 0.664 x 10^(-8) in scientific notation.
To divide the numbers in scientific notation, you subtract the exponents and divide the coefficients.
Given:
3.2 x 10^4 ÷ 4.82 x 10^12
Step 1: Divide the coefficients:
3.2 ÷ 4.82 = 0.6635 (approximately)
Step 2: Subtract the exponents:
10^4 ÷ 10^12 = 10^(4-12) = 10^-8
Step 3: Combine the results:
0.6635 x 10^-8
The final answer in scientific notation is approximately 6.635 x 10^-9.
To divide numbers in scientific notation, we divide the decimal parts and subtract the exponent of the divisor from the exponent of the dividend. Let's solve the problem step by step:
Step 1: Divide the decimal parts: 3.2 ÷ 4.82 = 0.6639 (rounding to four decimal places)
Step 2: Subtract the exponent of the divisor from the exponent of the dividend:
(10^4) ÷ (10^12) = 10^(4-12) = 10^-8
Step 3: Combine the decimal part and the exponent:
0.6639 × 10^-8
Therefore, the result is 0.6639 × 10^-8 in scientific notation.
