Question

3^-7 x 10^-7 x 125 / 5^-6 x 6^-6

don't answer if you don't know please​

Answer 1

Answer:

2* 10^-9

Step-by-step explanation:

We can solve this using the law of exponents

Step 1- 3^-7 * 10^-7 * 5^3 / 5^-6 * 6^-6.... ( write 125 as 5^3)

Step 2- ( 3 * 10 )^-7 * 5^(3+6) * 6^-6 .. (took the power, -7 common) and ( took 5 common)

30^-7 * 5^9 * 1 / 6^6

Step 3- 1 / 30^7 * 5^9 * 1/ 6^6

1/21870000000 * 1953125 * 1/46656

8.93* 10 ^-5 / 46656

1.91 * 10^-9

approx. 2* 10^-9

The other way you can do it is by cancelling out in the step 3.
