What is the value of the expression All of 2.8 multiplied by 10 to the power 7 over all of 1.4 multiplied by 10 to the power 3?
2.0 × 104
2.0 × 1010
1.4 × 104
1.4 × 1010
(2.8 * 10^7)/(1.4 * 10^3)
= (2.8/1.4)*10^(7-3)
= 2.0*10^4
To find the value of the expression, you can simplify the division by dividing the numbers outside the exponents and then subtracting the exponents.
In this case, the expression is (2.8 * 10^7) / (1.4 * 10^3).
To divide the numbers outside the exponents, you divide 2.8 by 1.4, which gives you 2.
To subtract the exponents, you subtract 7 from 3, which gives you 4.
Therefore, the simplified expression is 2 * 10^4.
In scientific notation, this can be written as 2.0 × 10^4.
So the correct answer is 2.0 × 10^4.
