Question

(perform the indicated computations. write the answer in scientific notations)
(4X106)−1

Answer 1

the 6 and the -1 represent the exponent. I just copy and past :P

Answer 2

I mean paste instead of the word past. lol

Answer 3

1/4000000 = 2.5 × 10^-7

Answer 4

OTL. sorry i mean. 4 * 10^-6

Answer 5

How did get 2.5 part?

Answer 6

no...actually i mean 2.5*10^-7. fail :(

Answer 7

you get this --> 1/4000000 so that gives 2.5 * 10^(-7) because
1/4 = .25 .... now tack on 6 extra zeroes. to get .2500000000, then move to the right, so 2.5 * 10^-7

Answer 8

oh I see now, thanks Ronncc.:)

Answer 9

\[(2^{-1}x ^{-2}y ^{-1})^{-2}(2x ^{-3}y)^{-2}(16x ^{-3}y ^{3})^{0}/ (2x ^{-3}y ^{-5)^{2}}\]
