Answer:
1.5 x 10⁵
Step-by-step explanation:
We use scientific notation to write huge ( or micro ) numbers as easily as possible. To do that, we use the following notation: a x 10ᵇ
Take 150,000, and put a decimal right between the 1 and 5, like so:
1.50000
Now simply count the numbers after the decimal:
1 . 5 0 0 0 0
1 2 3 4 5
That's five places, or numbers, after the decimal, and now we can use the notion mention earlier, a x 10ᵇ
So a = 1.5 and b = 5, and now we can combine the whole thing, so 1.5 x 10⁵
We can double check if needed/desired by doing the following
10⁵ = 100,000 x 1.5 = 150,000
