In mathematics, a proof is a sequence of statements given to explain how a conclusion is derived from premises known or assumed to be true. The proof attempts to demonstrate that the conclusion is a logical consequence of the premises, and is one of the most important goals of mathematics.

In mathematics, algebra is one of the broad parts of mathematics, together with number theory, geometry and analysis. In its most general form, algebra is the study of mathematical symbols and the rules for manipulating these symbols; it is a unifying thread of almost all of mathematics.

All right, So our question wants us to find the number of significant figures in each of the following numbers listed here is a through G. And I wrote the numbers. We want to find the significant figures for in Red, and I will write the amount of significant fingers that they have in black. So our first number for part is 214 sort of three numbers. They're all numbers are important numbers, so there are gonna be three significant figures. Okay, Our 2nd 1 is 81.60 Now there is a zero, but that zero is to the right of the decimal place tacked on at the end. So that number is still significant. So there are four significant figures in this scenario here, 7.3 We can't get rid of any of the numbers. They're all important. So there are three significant figures here for Part D. Well, we have 0.3 but we could move that decimal place over and write that as three times 10 to the minus two. So there is on ly one significant figure in this scenario because all the zeros are to the left of our number. Here again, All the zeros to the left of the digits of the numbers that aren't zero are irrelevant. We could move that over, and we have eight and six that are too significant numbers. So there are two significant digits here in party for part F. Again, we have four. All four are important. So we have four significant digits for part F. And then lastly for part G, we have a CE 87. I'm sorry. 716,700. Well, we could move the decimal place over here, which is written to the right of the zero. We could move it over to one two, and we have 87. We could write that as 87 times 10 to the too. So we have two significant figures there. The eight in the Senate. So there we are,
