Answer:
2 x 10^16
Step-by-step explanation:
[tex](1.3\times 10^{12})n=(2.6\times 10^{-4})[/tex]
Divide both sides by the coefficient of n.
[tex]n=\frac{2.6\times 10^{12}}{1.3\times 10^{-4}}[/tex]
The answer can be found by doing two calculations:
Divide 2.6 by 1.3 to get 2.
For the powers of 10, divide [tex]10^{12}[/tex] by [tex]10^{-4}[/tex] by subtracting exponents.
12 - (-4) = 12 + 4 = 16.
The answer is
[tex]n=2\times 10^{16}[/tex]
