How do you solve scientific notation
dmitriy555 [2]

Scientific notation consists of a coefficient (here 5.14) multiplied by 10 raised to an exponent (here 5). To convert to a real number, start with the base and multiply by 5 tens like this: 5.14 × 10 × 10 × 10 × 10 × 10 = 514000.0. Multiplying by tens is easy: one simply moves the decimal point in the base (5.14) 5 places to the right, adding extra zeroes as needed.     

<span>Convert from Real Number to Scientific Notation:      </span>

Here we wish to write the number 0.000345 as a coefficient times 10 raised to an exponent. To convert to scientific notation, start by moving the decimal place in the number until you have a coefficient between 1 and 10; here it is 3.45. The number of places to the left that you had to move the decimal point is the exponent. Here, we had to move the decimal 4 places to the right, so the exponent is -4.

if someone could please explain to me how to get the right answer on these i would really appreciate it
Law Incorporation [45]
You’re finding the least common denominator do you have to find what number the denominators can go into evenly. For example number one: 4 and 6 go into 12

1/4, multiply both top and bottom by 3.
That will give you 3/12

Now te same for 5/6. Now multiply both top and bottom by 2 and the equals 10/12

Final answer 3/12, 10/12.
If you need more help just comment! :)
