Question

Finally, consider the expression (6.67 x 10^-11)(5.97 x 10^24)/(6.38 x 10^6)^2 Determine the values of a and k when the value of this expression is written in scientific rotation. Enter a and k, separated by commas.

Answer 1

Explanation:

We need to find the value of following expression :

$\dfrac{(6.67 \times 10^{-11})(5.97 \times 10^{24})}{(6.38 \times 10^6)^2}$

Firstly, solving the numerator of the above expression :

$=\dfrac{39.8199\times 10^{-11+24}}{40.7044\times 10^{12}}\\\\=\dfrac{39.8199\times 10^{13}}{40.7044\times 10^{12}}\\\\=9.7827$

Rounding off the result = 9.78

In scientific notation : $9.78\times 10^0$

The value of a = 9.78 and k = 0.
