Question

how do you determine the value of the unknown exponent in the equation 9700 divided by 10? = 0.97?

Answer 1

We need to find the exponent of 10 of the equation :

$\frac{9700}{10^x}=0.97$

so,

$\begin{gathered} 9700=0.97\cdot10^x \\ \\ 10^x=\frac{9700}{0.97}=10000=10^4 \\ \\ 10^x=10^4 \end{gathered}$

so, x = 4

so, the value of the unknown exponent = 4
