Question

Express this number in scientific notation:19 hundred-thousandths

Answer 1

Recall that 1 hundred-thousandth in scientific notation is:

`1*10^(-5).`

Now, 19 hundred-thousandths is 10 one hundred-thousandths added to 9 one hundred-thousandths which is:

`10*10^(-5)+9*10^(-5)\text{.}`

Simplifying the above sum we get:

`1.9*10^(-4)\text{.}`

Answer:

`1.9*10^(-4)\text{.}`
