Which shows the expression below simplified? NOTE- This isn't the actual problem. I have replaced it with other numbers, and some numbers might not fit for the equation. If you notice that it doesn't go or seem right for this equation, please tell me! The equation and answers will be typed in because I cant type them correctly for this equation.

$0.00028\div(7\times10-^4)$

OpenStudy (zephyr141):

can you use a calculator? if not you have to rewrite 0.00028 into scientific notation. you can make it $\frac{ 28*10^{-5} }{ 7*10^{-4} }$ divide that out. 28/7 and you're left with that answer times 10^(-1)
