Question

how do you write 0.000078329 in scientific notation? × 10

Explanation:

Step1: Determine the coefficient

The coefficient should be a number $a$ such that $1\leqslant|a|< 10$. For the number $0.000078329$, we move the decimal point 5 places to the right to get $a = 7.8329$.

Step2: Determine the exponent of 10

Since we moved the decimal point 5 places to the right for a number less than 1, the exponent $n$ of 10 is negative. So $n=-5$.

Answer:

$7.8329\times 10^{-5}$
