Verbal
Explain why we can always evaluate the determinant of a square matrix.
A determinant is the sum and products of the entries in the matrix, so you can always evaluate that product—even if it does end up being 0.

in what situation (s) would be the use of a scanning electron microscope be ideal and why?
A scanning electron microscope (SEM) is ideal for situations requiring high-resolution imaging of surfaces. It is commonly used in materials science, biology, and geology to examine the topography and composition of samples at a nanoscale level. SEM is particularly useful for studying fine details,
