[tex](5*10^{-7} )*(3*10^{6} ) = (5*3) *(10^{-7} *10^{6} ) = 15*(10^{(-7) + 6} ) = 15 * 10^{-1} =0.15*10^{1}[/tex]

Hope that helps!

Answer:

1.5

Step-by-step explanation:

First I convert it using the negative exponent rule

so 10^-7 becomes

   1

 ------

 10^7

(Dont ask how the negative exponent rule works i have no clue to be honest)

Now we have to do the 10^7

10^7 = 10000000

So the fraction is now

            1

------------------------

   10000000

What we have above equals 0.00000010

So we got that part now we have to do

5 * 0.00000010 = 0.00000050

So now we have (0.00000050) x ( 3 x 10^6)

Its fairly easy from here

first we do

10^6 = 1000000

then we do

3x1000000 = 3000000

Now we have

(0.00000050) * (3000000)

The parentheses are useless at this point so we can just remove them

0.00000050 * 3000000 which gets us to.. 1.5

I hope this is better than my last answer lol.. this hurt my head
