Answer:

The total magnification of a refracting telescope is -75

Explanation:

f₀ = 30 cm

[tex]f_{e}[/tex] = 0.40 cm

Magnification in telescope => m = - f₀ /  [tex]f_{e}[/tex]

                                                    m = - 30 / 0.040

                                                    m = -75

Magnification in telescope = -75

The negative sign shows the image is inverted
