The mass of planet mercury is 3.3x10^23 kilograms the mass of planet jupiter is 5.8 x 10^3 times the mass of planet mercury. planet jupiter is 3.2×10^2 times the mass of planet earth.

1. using scientific notation what is the mass of planet jupiter?
2. using scientific notation what is the mass of planet earth?

it would take 7/10 of an hour too fill the pool.

step-by-step explanation:

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
