Question

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

Answer 1

Answer:

$x=9.78\times 10^0$

Explanation:

In this case, we need to find the value of expression :

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

On solving, we get the value of given expression as :

x = 9.7827

In scientific notation, we get the value of x as :

$x=a\times 10^k$

$x=9.78\times 10^0$

a = 9.78

k = 0

Hence, this is the required solution.
