Answer 1

@UnkleRhaukus

Answer 2

10^1=10
10^-1=0.1

Answer 3

so really the equation is 1.13 x 10 + 9.1 x 0.1 ?

Answer 4

so that means that this 4.1 x 10^4 - 1 x 10^3 is really 4.1 x 40 - 1 x 30 ?

Answer 5

10^4=10000≠40

Answer 6

10^x stands for 10 power x.
so 10^4 is 10 000 as noted by @UnkleRhaukus.

Answer 7

so 10^4 does = 40 ?

Answer 8

Some of this is coming back to me, I just want to be sure.

Answer 9

no. Basically the x is the number of zeros after 1.
10^x is 1 and then x zeros.

Answer 10

\[10^4=10\times10\times10\times10=100\times100=10 000\]

Answer 11

ohh okay, thank you (:
