4²-3+11-12 = 16-3+11-12 = 12

-68 I think

+ (plus) - (minus) / (divide) * (multiply) ^ (power) = (equals)

10-10 = 0.0000000001 or 1x10-10 in standard form.

Sound Intensity = Power / Area. So the more power delivered to a smaller area the greater the intensity.

Light intensity increases as well

Intensity = Power / Cross sectional area

minus 8..

Sound Intensity = Power / Area. So the more power delivered to a smaller area the greater the intensity.

6 to the power of 6 minus 3 to the power of 3 = 46,629

Power P is measured in watts and intensity I (power per area) is measured in power per square meter if you think e.g. of sound.

12 x 12 is written as 122

Intensity=|E|2 where, E=Electric field amplitude.Power=|Intensity|*Area

That ist the energy of noise. Sound intensity = sound power divided by area.

49 - 8 - 6 = 35

49 - 8 - 6 = 35

2x to the fourth power minus 162 equals -146

Intensity can be measured by converting units of electrical power in to decibels.

Sound intensity or acoustic intensity(I) is defined as the sound power Pacper unit area A. The usual context is the noise measurement of sound intensity in the air at a listener's location.

It is a trillion.

That depends what the value of A is.
