Simplify. Write in scientific notation. (9 × 10^–3)^2
12345.67901 or in scientific, it is equal to: 1.234567901*10^5
were did all those numbers come from??
Sorry, i read that as a -2 in the end, and yea, what you got is right.
okay good :) now here is the most hard one.\[Evaluate \frac{ 1 }{ 2} a ^{-4} b ^{2} for a = –2 and b = 4.\]
What did I say about using the equation editor? Math ONLY. Anyhow, just plug in for the calculator and you get: \[-.2\] or \[-\frac{ 1 }{ 5 }\]
neither of those are my options. 2 \[\frac{ 1 }{ 2 }\] 3 4
Hmm, can I see the original question then? Like a pic?
Actually, I see. Your writing messed me up again. It should be 1/2.
