Solve the following problem and select the correct (4.5 x103)(3.5 x102) 15.75 x105
1.575 x106
16 x105
O 1.6 x106

D: 1.6 x 10^6

Explanation:

(4.5 x103)(3.5 x102

Multiply

4.5 x 3.5 = 15.75

Now add 10^3 + 10^2 because we are finding the product of this.

10^3 + 10^2 = 10^5

Use sig figs

15.75 rounded to the whole number is 16.

A scientific notation always has to only have the tenths place only.

Change 16 to 1. 6

Then change 10^5 to 10^6

And your final answer would be 1.6 x 10^6.

Hope I helped!

hey there!

mass = 6.75 g

volume =   9 cm³

therefore:

d = mass / volume

d   = 6.75 / 9

d = 0.7 g/cm³

answer b

5.6⋅10−^19  j

do you need the explaination?
