Scientific notation is a way of writing numbers in a form of a decimal multiplied by an exponent of 10.
For these, the exponent will be negative, since they're teeny tiny decimals, and we'll have to move the decimal point back to the right.
0.00000012 will become 1.2* 10^{-7}
This is because the decimal point is moved seven places to the right of where it originally was.
0.000005008 will become 50.08* 10^{-7}
Again, this is because the decimal point is moved seven places to the right of where it originally was.
So, your scientific notations are 1.2* 10^{-7} and 50.08* 10^{-7}

Answer:

Ammm, I think the answer you have is wrong, but what I really think is that the equations you put in are not the right ones because the answer for these is "ugly" (decimals etc...). Want to check your equations?

Step-by-step explanation:

Here is a step by step explanation to your equations (I assumed +3z for the second but you can change it). You can edit it for your equations if you want to.

Tim scored 35, 38, and 36 points on three tests. How many points should he get on the fourth test to get an average score of 40?
My name is Ann [436]
I think 51 because if you were to do it reverse then it would be 40x4=160 then -35-36-38 it would be 51.

1/2 - 3/4 equals what
n200080 [17]
1. Method 1: By Listing MultiplesList out all multiples of each denominator, and find the first common one.

2: 2 , 4

4: 4
Therefore, the LCD is 4

Method 2: By Prime FactorsList all prime factors of each denominator, and find the union of these primes.
Therefore, the LCD is <span>2 x 2 = 4
</span>
2. <span>Make the denominators the same as the LCD

</span>\frac{1 x 2}{2 x 2} -  \frac{3}{4}
<span>
3. </span><span>Simplify. Denominators are now the same.

</span>\frac{2}{4} - \frac{3}{4}

4. Join the denominators

\frac{2-3}{4}

5. <span>Simplify

</span>-\frac{1}{4}
<span>
Done! :) </span><span>Decimal Form: -0.25</span>

The sum of three consecutive even integers is -78, what are the integers ?
Digiron [165]
First, you need to analize and understand the problem, then you must choose and strategy. There is a wide variety of strategies to solve a mathematical problem, in this case, you can use the following, which is based on the information given above:
 1. You have that t<span>he sum of three consecutive even integers is </span>-78<span>, therefore, you can given the variable </span>x&#10;<span> to the first integer, the second even integer is </span>x+2<span> and the third one is </span>x+4&#10;<span>.
 2. Calculate x:
 </span>x+(x+2)+(x+4)=-78<span>
 </span>3x+6=-78
<span> </span>x=-28&#10;<span>
 </span>x+2=-28+2=-26&#10;<span>
 </span>x+4=-28+4=-24&#10;<span>
 Therefore, the answer is:</span>-28,-26,-24&#10;
