, the expression z ^-44 can be simplified to

1/ (z²)²

Step-by-step explanation:

z⁻⁴= 1/z⁴  (laws of exponents ) when a term with positive exponent is written in reciprocal the sign of its exponent changes

= 1/ (z²)²  Further breaking the 4th power

step-by-step explanation:

divide, then simplify your answer.

1. make -15.66 ÷   5.8 a fraction. then divide.

2. simplify.  

3. final answer.  

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
