Not necessarily is x35 when it says 35mm equivalent. This is because "35mm" refers to the format and not the focal length equivalent.
The 35mm equivalent of 1x optical zoom of a camera depends on the camera in question and it ranges mostly from 35-38mm. So for a camera such as my Nikon Coolpix 5700, the 1x optical is 35mm and so my maximum 8x optical zoom is 8x35 = 280mm equivalent on the 35mm format. For the Fuji F10, the 1x is 36mm and so its 3x optical is 3x36 = 108mm equivalent on the 35mm format. For the Sony F717, its 1x is 38mm and its 5x optical zoom is 5x38 = 190mm.
I suppose the above is what the threadstarter wants to know.
To complicate matters, such long 35mm equivalent zoom is achieved only because sensors of these camers are much smaller than the full 35mm format frame size. The zoom is only apparent and not actual. The actual focal length of my Nikon Coolpix 5700 at 8x optical is 8x8.9 = 71.2mm only even though it's 280mm equivalent on the 35mm format. So it appears to have the same magnification as a 280mm lens on a 35mm full frame size camera but the image formed in side the camera is actually similar in size to using only a 72mm lens on a 35mm full frame size camera. The image appears to be zoomed by a 280mm lens only because the CCD sensor is much smaller in the Coolpix 5700 than a full frame 35mm format camera. So the details that can be captured by my Coolpix 5700 is far lesser than what a DSLR can. Most DSLRs use APS-sized sensor and have a crop factor of 1.4-1.6x. So a 200mm lens used on such DSLR has a focal length of 280-320mm on a 35mm equivalent format although its actual focal length doesn't change and is still at 200mm.
In sum, comparing the focal lengths between consumer compact cameras and DSLRs is a little more complicated than what appears on the surface.
