Question

i need answers fast for these questions or atleast some of them i don't have that much time left so please hurry (will post questions)

Answer 1

for \(8.2\times 10^{-5}\) move the decimal 5 places to the left

Answer 2

so it's 0.000082? thanks :]

Answer 3

yes

Answer 4

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

Answer 5

im a little confused.. so does that mean 2p0 doesnt equal to 1? so the answer would be C?

Answer 6

\(2p^0=2\times 1=2\)

Answer 7

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

Answer 8

You can apply the same principle to question 4

Answer 9

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

Answer 10

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

Answer 11

For question 6...i believe the logical answer would be that it takes \(\frac{1}{2000}\) of a second to blink?

Answer 12

For question 7, you can use the same principle from question 3&4

Answer 13

And finally for question 8, hypothetically, the bigger the exponent, the bigger the number in this case

Answer 14

thank you so much!
