Respuesta :
The dust particle is seen to have 400 times more mass than the pollen particle
How to use rule of exponents?
We will use the scientific notation.
For example, 0, 002 can be written as:
2 × 10³
Where;
3 is the number of times the comma (,) must be run to the right to convert the quantity 0, 002 to 2.
0, 002
0| 0 0 2
0 0| 02 -----------1
0 0 0|2------------2
0 0 0 2| ----------3
Thus, for the given expression:
Powder particle 0.000000778 g
It can be written as: 0.0000008 g = 8 × 10⁻⁷
b = -7
In the same way
Pollen grain of 0.00000000155 g
It can be written as:
0.000000002 g = 2 × 10⁻⁹
To know how big the mass of the dust particle is with respect to the pollen, we have;
(8 × 10⁻⁷)/(2 × 10⁻⁹) = 400
Complete question is;
The table below shows the approximate masses of a dust particle and a grain of pollen.
Dust Particle 0.000000778 g
Grain of Pollen 0.00000000155 g
The mass of a dust particle can be estimated and written in the form a × 10^b, where a = 8 and b =
The mass of a grain of pollen can be estimated and written in the form a × 10^b, where a = 2 and b =
Based on the estimates, the mass of a dust particle is approximately BLANK
times larger than the mass of a grain of pollen.
