(would like someone who has not tried to solve this before)

Express in siimplest form. Positive exponents only. SHOW EVERY STEP! Rationalize denominator if it has a radical. solution should be one fraction:

3 (x ^-1 z ²) + x ^-1z ^-6

Solution

3(x^-1z²)+ x^-1z^-6

first we have to convert negative exponents to positive exponents

a^-b=1/a^b

3(z²/x) + 1/xz⁶

(3z⁸+1)/(xz⁶)
