Question

how do you write 190 in scientific notation? × 10

Explanation:

Step1: Rewrite number as product

Scientific notation is of the form $a\times 10^{n}$, where $1\leq a<10$. For 190, we can write $190 = 1.9\times100$.

Step2: Express 100 as power of 10

Since $100 = 10^{2}$, then $190=1.9\times 10^{2}$.

Answer:

$1.9\times 10^{2}$
