5 EXPOENT 2 · 10
2 EXPONET 2 · 5
2 EXPONET 2 · 5 EXPONET 2
2 EXPONET· 5 EXPONET 2


17.
Which number is closest to zero on a number line?

A.1/12
B.10/101
C.1/10
D.1/4

Answer 1

270 = 2 * 3^3 * 5
A: 2*3*5, 2*3^2*5, 2*3*5*13 Nope
B: 2*3^2, 2*3*5, 2*3^3 Yes
C: 5^2,5^3,2^3*3*5 Nope
D: 2,3^2,3*5 Nope

14: A
did you really have a problem determining which numbers were greater than others?

15: 50 = 2*5^2, so the last, ignoring the EXPONENT with no value on the right.


17:
1/12 = 0.083
10/101 is almost 10/100 = 0.100
1/10 = 0.100
1/4 = 0.250

So, which do you think is the smallest?

Answer 2

I'm still not sure which one is the smallest still I'm doing the same test
