Which digits in a measurement are always significant? check all that apply. zeros to the left of the decimal point zeros between nonzero numbers zeros to the right of the decimal point nonzero numbers zeros to the right of both the decimal point and a nonzero number zeros to the left of both the decimal point and a nonzero number

zeros to the left of the decimal point: if you have a number like 000000.3, there are a lot of zeros that dont meaning anything. But if you have 100000.3, the zeros have important information.

zeros between nonzero numbers: This obviously matters a lot, isn't the same 303 than 33.

zeros to the right of the decimal point . can matter or not, if you have 10.00000000... the zeros don't are significant, so you can only write 10, but if you have 10.000004, is important to know that are 5 zeros before the first non zero decimal appears.

nonzero numbers. Well, this are significant almost always, the only situation where you can discard them is if they are to the right of the first nonzero number after the decimal point.

zeros to the right of both the decimal point and a nonzero number: Discard them, don't really aport nothing

zeros to the left of both the decimal point and a nonzero number: i kinda discussed them in the zeros to the right of the decimal point  part, this zeros are significant.

i would think it's food chain
