Does anyone know this?

The correct answer is B or A, but I'm more on B side

Step-by-step explanation:

Hope this helps u (✿◡‿◡)

It's A

Step-by-step explanation:

41x41^2 is equal to 41^3, and (41x41)^2 is equal to 41^4, so both expressions are not equivalent to each other.

angle addition postulate

2x=56

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
