Question

how to evaluate exponent question

Answer 1

5^-2 - 5^-1 / 5^-2 + 5^0

Answer 2

5^-2 = 1 / 5^2 = 1/25

5^-1 = 1 / 5^1 = 1/5

5^0=0

So what you have is,
\[\frac{1/25-1/5}{1/25+1}\]

Answer 3

can you take it from here, or in need more help ?

Answer 4

I meant 5^0=1

Answer 5

i can take it from here thanks so much!

Answer 6

well its all depending on your exponent question but still if you need help i could help you too

Answer 7

Answer 8

well, not really... not in this case.

Answer 9

yea i agree its not really possible but no.

Answer 10

\[\frac{1/25-1/5}{1/25+1}\]
\[\frac{1/25-5/25}{1/25+25/25}\]
\[\frac{-~4/25}{26/25}\]
\[\frac{-~4}{26}\]
\[-\frac{~2}{13}\]

Answer 11

that's all :)
