Write these numbers in scientific notation... 1) 2,000,000 2)0.0000007

simplify the expressions... 1. (x^3)^5 2. (y^4)^5 3. 4^8/4^2(this is a fraction) 4. b^2/b^4(this is a fraction) 5. 28xy^7/32xy^12(this is a fraction) Please show me step by step because I am not really understanding these types of problems...

In my textbook, I was given these directions to follow when doing these problems: **Multiply. Express each result in Scientific Notation** 1. (4 x 10^9)(6 x 10^6) My work: (400,000,000)(600,000)= 240,000,000,000,000 My answer: 2.4 x 10^14 Am I right? 2. (...

Wow...that was rude. I didn't mean to make it sound that way, I was just confused... o_o sorry

Okay, my bad, so sorry. I am just having a difficult time simplifying the expressions that involve fractions w/ exponents. I have my textbook and I have been working on it for awhile but I need more guidance on how to do it...I can be a slow learner somet...

Oh okay! That actually makes more sense...Thanks :)

wait no...#1 is 2.4 x 10^16 and #2 is 1.8 x 10^11
