Wat is the scientific notation for 0.00000012 and 0.000005008
gtnhenbr [62]
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:

1.  (3/2)

2. (20)

3. (3)

4. (-9/5)

5. (-8/7)

6. (-2/3), (4)

Step-by-step explanation:

1.                          2.                        3.                          4.

x         3                   12         3               x           1                x + 3        3

/    =    /                     /     =    /                /    =      /                   /     =     /

4         8                   x           5              9           x                   2           5

8x = 12                    60 = 3x                  x² = 9                      5x + 15 = 6

÷8    ÷8                   ÷3    ÷3                   x = √9                          -15     -15

                                                                                                5x = -9

x = (3/2)                   x = 20                  x = 3                           ÷5    ÷5

                                                                                                  x = (-9/5)

5.                             6.

4 - x          3                   1               x - 3

  /       =     /                   /        =        /

 12            7              2x + 1               9

28 - 7x = 36                   9 = 2x^2 - 5x - 3

-28         -28                 + 3                    + 3

                                     12 = 2x^2 - 5x

-7x = 8                          -12                   -12

÷-7   ÷-7

                                       2x^2 - 5x - 12 = 0

x = (-8/7)                      

                                       -b +-√b^2 - 4ac

                                                     /                = -(-5)√-5^2 - 4 (2)(-12)

                                                    2a                                /

                                                                                      2(2)

                                             

                                          = 5-+√121        5 - 11        -6

                                                 /         =        /       =    /       = (-2/3)

                                                -4                 4             4

                                                            =     5 + 11          16

                                                                       /      =       /    = (4)

                                                                      4              4

I hope this helps!
