Answer:

Step-by-step explanation:

To simplify this we factor the numerator and denominator separately
factor 4z^2 - 16z+15
We apply 'ac' method, 4* 15 = 60
-10 * -6 = 60
-10 - 6 = -16
Now we split -16z using factors -10z -6z

Take out GCf from first two terms and last two terms

(2z-3)(2z-5)
factor 2z^2 - 11z+15
We apply 'ac' method, 2* 15 = 30
-5 * -6 = 30
-5 - 6 = -11
Now we split -11z using factors -5z -6z

Take out GCf from first two terms and last two terms

(z-3)(2z-5)
Now we replace the factors

Cancel out 2z-5 at the top and bottom

Answer:
a = 1/64
Step-by-step explanation:
3 + 4 a ^ 1/6 = 5
1. move constant to the right side and change its sign
4 a ^ 1/6 = 5 - 3
2. using <em>a</em><em> </em><em>^</em><em> </em><em>m/</em><em>n</em><em> </em><em>=</em><em> </em><em>n√a^m</em><em> </em><em> </em>transform the expression
4 6√a = 5 - 3
3. Subtract the numbers
4 6√a = 2
4. Divide both sides of the equation by 4
6√a = 1/2
5. Raise both sides of the equation to the power of 6.
a = 1/64
