Question

power 2 x minus 2 power x + 3 + 2 power 4 equal to zero find the value of x

Answer 1

Given: the correct term will be: 2 power 2 x minus 2 power x + 3 + 2 power 4 equal to zero.

To find: The value of x?

Solution:

• Now we have given the equation in the form of words as:

             2 power 2 x minus 2 power x + 3 + 2 power 4 equal to zero

• Lets write it in numerical form, we get:

            2^(2x) - 2^(x + 3) + 2^4 = 0

• Now we can rewrite it as:

            2^(2x) - 2^(x + 3) + 2^4 = 0^1

• Now taking all the powers together, we get:

            2x + x + 3 + 4

             3x + 7  = 1

            3x + 7 = 1

            3x = 1 - 7

            3x = -6

            x = -6/3

            x = -2

Answer:

              So the value of x is -2.
