Respuesta :

In the question 16 = −5 + z∧4, z is the only unknown value. It can be solve as follows, 
 
16 = −5 + z∧4
z∧4 = 16+5
z∧4 = 21

Find the 4th root on both side of the equation, 
z = the 4th root of 21
   = 2.140695143

To the nearest tenth, z = 2.1

Answer:

The answer is 69.

the equation is setup like this

16 = -5 + z / 4

/ = divide

-5 + z are added together to then be divided by 4 and to complete the equation.

To get the answer you then follow the basic equation it gives you.

You put 69 where z is and you add -5 which turns 69 into 64.

You then divide 64 by 4 and you get 16. so 16 = 16

so this  16 = -5 + z / 4  turns into this  16 = 16

The answer to complete this equation is 69!

Z = 69
