second one is a bit tricky \[x^0=1\] but for example \(5x^0=5\times 1=5\) not \(5x^0=1\)

im a little confused.. so does that mean 2p0 doesnt equal to 1? so the answer would be C?
anonymous
  • anonymous
\(2p^0=2\times 1=2\)

Third one you need to realize that: \[x^{-a}=\frac{1}{x^a}\] So \[mn^{-7}=m*\frac{1}{n^7}=\frac{m}{n^7}\]

You can apply the same principle to question 4

okay thank you :] i'll work on that for a bit

For question 5, I believe the answer is B since there is five significant digits and you require to move the decimal over 7 spaces
anonymous
  • anonymous
For question 6...i believe the logical answer would be that it takes \(\frac{1}{2000}\) of a second to blink?
anonymous
  • anonymous
For question 7, you can use the same principle from question 3&4
anonymous
  • anonymous
And finally for question 8, hypothetically, the bigger the exponent, the bigger the number in this case
