Help plz im almost out of time

the correct answer is below

Step-by-step explanation:

11p7-9p5+8p³-4p7+13p5-5p³

11p7-4p7-9p5+13p5+8p³-5p3

=7p7+4p5+3p³

note: I multiply all the terms in the second parentheses by the negative sign that is beside it.

what is the information provided?

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
