Question

How do I do this. I don’t understand how to move place values

Answer 1

For this case we must indicate the value of the following expression, expressed in scientific notation:

`(1.2 * 10^(-3)) * (1.1 * 10^(8)) =`

We have that for multiplication properties of powers of the same base, the same base is placed and the exponents are added:

`a ^ n * a ^ m = a ^ {n + m}`

Then, rewriting the expression we have:

`(1.2 * 1.1) * 10 ^(- 3 + 8) =\\1.32 * 10 ^ 5`

Answer:

`1.32 * 10 ^ 5`
