Question

Some facts about powers of ten are shown. Use what you know about powers of ten to enter numbers that make the equation true.

Answer 1

Answer:

Final answer is 0.0000079. The blank under the fraction will be 1,000,000.  

Step-by-step explanation:

If you look at the example given, it uses 10^-2 = 1/100. It works the same for  

10^-6. if the exponent is negative, the decimal moves to the left. If the exponent is positive, the decimal moves to the left. You take 1.0 and move the decimal 6 places to the right to get the fraction 1/1,000,000. For the final answer, take 7.9 and move the decimal 6 places to the left.

Answer 2

Answer:

1/ 1000000 (6 noughts)

Step-by-step explanation:

7.9 * 10^-6 = 0.0000079 = 79/10000000  (7 noughts) the square of this fraction = 0.0028   however we are asked for the fraction of 10^-6 so 10/10 = 1 and 10000000/10 = 1000000  =  1/ 1000000 (6 noughts)
