What are the solutions of the equation?
Solvex2 - 16 = 0.
1. Isolate x2 : x2 = 16
2. Apply the square root property of equality:
Vx2 = + 5
O x = 5, and x = -2
O re and x = -
Ox= 15 and x = - 16
0 x = 4 and x = -

-1/2 +2

step-by-step explanation:

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
