Answer:
not capable of being imagined or grasped mentally; unbelievable.
Explanation:
not capable of being imagined or grasped mentally; unbelievable.
First look at the numbers. Notice that this is in decimal form. When it's in decimal form, you have to move the decimal to the right until you see a different number other than 0. Therefore, starting with decimal, move it to the right 4 times since a # bigger than 0 is there.
0.000371
- - - -
The answer will be 3.71^-4
If it is in decimal form, the power will be a negative
I think the answer is bio mass
bio:life
mass:total
