I'd suggest you not use " x " to indicate multiplication. Usually, " x " is used as a variable name, not as an operator. Use " * " to indicate multiplication:
2*10^(-2).
Note that 10^(-2) is smaller than 10^(-1), so eliminate 2*10^(-2) as an answer choice. Then decide which of the coefficients of 10^(-1) is the largest:
3.2, 3, 2.5.
3.2 is the largest.
Thus, the final answer is: "The largest number here is 3.2*10^(-1)."
Here is your answer:
Lets solve each equation to find out which has the greater value:
A. 2 x 10^-2
It's negative so move to the left:
= .002
B. 3.2 x 10^-1
It's negative so move to the left:
= .32 <---- Your answer.
C. 3 x 10^-1
It's negative so move to the left:
Remember each full number has a decimal point that you can't see:
= .3
D. 2.5 x 10^-1
It's negative so move to the left:
= .25
Therefore the answer is option B "3.2 x 10^-1."
Since how:
.32 > .002
.3 < .32
.32 > .25
Hope this helps!
