For what value of x is 896Z15 225 25 11 XV14z? Assume z+0.

Karolina [17]

Answer: Value of x is, 8

Step-by-step explanation:

Given: ,.....[1]

To find the value of x:

Using exponent rules:

Taking square both sides in [1] we have;

Simplify:

Multiply both sides by we get;

Simplify:

x = 8

Therefore, the value of x is, 8
