uh hi is it ok if someone can do my ixl for me:
When you go on go to math at the top, then seventh grade and scroll and do: CC.8, R.19, and N.2. I WILL MARK BRAINLEST TO WHO EVER GETS DOES IT FIRST AND A SCORE AT 85% or higher. One person at a time or it wont work

i think it is c, not positive though

step-by-step explanation:

3.how is solving radical equations different than solving linear equations?

step-by-step explanation:

.

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
