Answer:
a) 24×10^-7
Step-by-step explanation:
The number is ...
0.0000024 = 2.4×0.000001 = 24×0.0000001
The first of these equivalents can be written as ...
2.4×10^-6 . . . . matches no answer choice (correct answer)
The second of these can be written as ...
24×10^-7 . . . . matches choice (a)

Usually "scientific notation" requires there be one digit left of the decimal point in the mantissa. As we have noted above, no offered answer choice matches this form. The only choice that is equivalent to the given number is the one shown above.
First let’s write down what 2 fourth would look like. It would look like 2/4 (on the computer/phone it looks a little different, if you were to write it out the 2 would be over the 4). Now think is there anything that 2 and 4 can both be divided by. The answer is yes! They can both be divided by 2. So divide them both by 2. 2 divided by 2 is 1, and 4 divided by 2 is 2. So your answer becomes 1/2, or one half. There is nothing else they can both be divided by so that’s your final answer.

tell me if I got it wrong
I don’t know if these are options for the drop box thing but SAS (side angle side), makes the triangles congruent
