Well we have 50-6=44, So out of those what numbers are greatter than that

anonymous · Answer

All of the numbers that are "subtracted" are actually exponents @TacoBellMan

amistre64 · Answer

the more negative an exponent is, the smaller the real value becomes

10^-2 > 10^-100

amistre64 · Answer

so, if we have any 10^-6, all exponents bigger than -6 are bigger by default, any exponents equal to -6 ... hmm

2(10^-1) [??]  5(10^-1)

2(10^-1)(10^1) [??]  5(10^-1)(10^1)

2 [??]  5

is just a comparison of the integer values

ahhhh well then amistre64 shall steer you right now   I apologize for my confusion

amistre64 · Answer

since 4 < 5,  i wouldnt pick that one to be bigger

anonymous · Answer

So A. B. and C.?

amistre64 · Answer

-8< -6  so not A

th epossibles are:

BCD  but one of those is a bust

amistre64 · Answer

a(10^-5)  > b(10^-8)

a(10^-5)(10^5)  > b(10^-8)(10^5)

a  > b(10^-3)  since a is >1  and b is a fraction <1 ...
