Write down the example of converting the two numbers to the same exponent: We conclude that the atom is the greater.

2'nd atom

Step-by-step explanation:

There are two atoms one weighs

6.022*10^-29 grams

another weighs

1.66*10^-17 grams

Which atom has a greater mass?

Work:

-29-(-17)=-12

-29 is 12 decimal places smaller than ^-17

0.000000000006.022*10^-17=1.66*10^-17

0.000000000006.022=1.66

0.000000000006.022<1.66

atom 1 < atom 2

We can conclude that the second atom is the greater.

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^

answer:

125 yards

explanation:

75+50=125. that is my answer
