Answer:
1/52
Step-by-step explanation:
2 to the fourth is 16, and 6 to the second is 36. However, since it's a negative exponent, you'd have to move it down to to the bottom of the fraction, creating 1/16+36, which makes 1/52.
To find a fraction between two fractions, all we need to do is make the sum of the numerators be the new numerator, and the sum of the denominators be the new denominator.(x) So, for example, a fraction between 7/13 and 6/11 is (7 + 6)/(13+ 11) =13/24.(x)
7/13 = .5384615(x)
6/11 = .545454(x)
13/24 = .541666�
Given that a/b < c/d, why is it true that a/b < (a+c)/(b+d)< c/d?

Answer : The correct answer is, -13000 g
Explanation :
Significant figures : The figures in a number which express the value -the magnitude of a quantity to a specific degree of accuracy is known as significant digits.
The rule apply for the multiplication and division is :
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
The given expression is:
![(9.1\times 10^4)(1.1\times 10^{-5})(\log 10^{-13})(1000)g](https://tex.z-dn.net/?f=%289.1%5Ctimes%2010%5E4%29%281.1%5Ctimes%2010%5E%7B-5%7D%29%28%5Clog%2010%5E%7B-13%7D%29%281000%29g)
As we know that,
![\log 10^{-13}=-13](https://tex.z-dn.net/?f=%5Clog%2010%5E%7B-13%7D%3D-13)
![\Rightarrow (9.1\times 10^4)(1.1\times 10^{-5})(-13)(1000)g](https://tex.z-dn.net/?f=%5CRightarrow%20%289.1%5Ctimes%2010%5E4%29%281.1%5Ctimes%2010%5E%7B-5%7D%29%28-13%29%281000%29g)
![\Rightarrow -13013g](https://tex.z-dn.net/?f=%5CRightarrow%20-13013g)
True value means, the rounding off the number. So,
![\Rightarrow -13000g](https://tex.z-dn.net/?f=%5CRightarrow%20-13000g)
Therefore, the correct answer is, -13000 g
