Final answer:
The expression is simplified by converting negative exponents into positive ones and applying the rule that any number to the power of 0 is 1. The resultant exponents for x, y, and z are positive, and for x, the exponent is 2 after reciprocating the base. For y, the exponent remains 3, and for z, it will be whatever Z represents.
Step-by-step explanation:
To simplify the given expression with positive exponents, let's break down the expression and deal with each part separately:
(2x2y3)-1 becomes 1/(2x2y3) and the exponents become positive
x70 becomes x0 as any number raised to the power of 0 is 1
760 becomes 1 for the same reason as above
For 260(x-2yZz), since anything raised to the power of 0 is 1, we ignore 260 and only consider (x-2yZz). The exponent of x here would be -2, but we need to make every exponent positive. We do this by reciprocating the base to get x2 in the denominator.
Combining everything, we have:
The exponent on x is 2.
The exponent on y is 3.
The exponent on z is not explicitly given in the question, but if Z represents the exponent, then that would be the exponent on z.
