$\huge\text{Hey there!}$

$\mathsf{7\times 10^{-4}}$

$\rightarrow\mathsf{7\times\dfrac{1}{10\times10\times10\times10}}$

$\mathsf{= \dfrac{7}{10\times10\times10\times10}}$

$\mathsf{10\times10\times10\times10=100\times100=10,000=\bf 10^4}$

$\mathsf{=\dfrac{7}{10^4}}$

$\mathsf{=\dfrac{7}{10,000}}$

$\boxed{\boxed{\large\textsf{Possible ANSWERS: }\mathsf{\bf {\dfrac{7}{10^4}\ or \ \dfrac{7}{10,000}}}}}\huge\checkmark$
