To divide numbers in scientific notation, you need to divide the coefficients (the numbers before the exponential terms) and subtract the exponents.
Given:
3.3 * 10^4 / 5.5 * 10^7
Dividing the coefficients:
3.3 / 5.5 = 0.6
Subtracting the exponents:
10^4 / 10^7 = 10^(4-7) = 10^(-3)
Combining the coefficient and exponent:
0.6 * 10^(-3) = 0.0006
Therefore, 3.3 * 10^4 / 5.5 * 10^7 = 0.0006.
divide 3.3*10^4 by 5.5*10^7

To divide numbers in scientific notation, we divide the two coefficients and subtract the exponent of the divisor from the exponent of the dividend.
Given:
3.3 * 10^4 / 5.5 * 10^7
Dividing the coefficients:
3.3 / 5.5 = 0.6
Subtracting the exponents:
10^4 / 10^7 = 10^(4-7) = 10^(-3)
Combining the coefficient and exponent:
0.6 * 10^(-3) = 0.6 * 1/10^3 = 0.6 * 1/1000 = 0.6 * 10^-3 = 0.6 * 10^(-3)
So, 3.3 * 10^4 / 5.5 * 10^7 = 0.6 * 10^(-3).
The correct answer is d. 6 * 10^(-3).
Given:
3.3 * 10^4 / 5.5 * 10^7
Dividing the coefficients:
3.3 / 5.5 = 0.6
Subtracting the exponents:
10^4 / 10^7 = 10^(4-7) = 10^(-3)
Combining the coefficient and exponent:
0.6 * 10^(-3) = 0.6 * 1/10^3 = 0.6 * 1/1000 = 0.6 * 10^-3 = 0.6 * 10^(-3)
So, 3.3 * 10^4 / 5.5 * 10^7 = 0.6 * 10^(-3).
The correct answer is d. 6 * 10^(-3).
