How many matrix multiplications required to compute matrix raise to the power n?

At most n-1. However, it can be a lot fewer.
For example, calculating A10 does not require 9 multiplications.
A*A = A2
A2*A2 = A4
A4*A4 = A8
A8*A2 = A10
Only 4 multiplications were required.

What is the power of a matrix?
If n is a natural number and M is a matrix, then Mn denotes the matrix M multiplied by itself n times. We can include n=0, but that is just the identity matrix. So the power of a matrix is very similar to the exponents that are used for numbers.
How can you compute the number of watts?
watts = volts x amps x power factor
Use the equation A r equals pi and r to the power of 2 to compute A 6?
113.04 - 113.1
How can you use 2 to the power of 2 to calculate 2 to the power of 3?
Simply multiply by 2 again. It's really only using 22 as a factor. As a general rule, an = a X a X a X ..... where the number of multiplications = (n-1).
How do you compute for watts?
Power (in watts) = energy (in joules) / time (in seconds). There are other formulae that involve watts as well, depending on the exact situation. For example, in electrical currents, watts = amperes x volts x power factor. The power factor is usually close to 1.
How do you compute for the power of a submersible pump?
To compute the power of a submersible pump, you need the pressure and the pump power.
How do you compute electrical power required for pumps?
In order to compute electrical power required for pumps, the following formula can be used. P(h)=q*p*g*h/3.6*10^6, where P is the hydraulic power, q is the flow capacity, p is the density of the fluid, h is the differential headÊand g is the gravity (9.81). Alternately, calculators can also be used.
What is the trace of a matrix to a power?
It is the diagonal entries of the matrix raised to a power.

Where do computing terminals with no power get their ability to compute?
Computing terminals without power do not have the ability to compute. Computing devices require electrical power to function and perform computations.

What is meant by susceptance matrix in dc load flow?
When you approximate resistance R to zero (because it's significantly less than a reactance of a power cable) the admittance matrix turns into susceptance matrix.
