NEED HELP WILL MARK BRAINLIEST IF CORRECT!!

A OR C

Step-by-step explanation:

1 Use Rule of One: {x}^{1}=xx

1

=x.

m=\frac{{y}^{2}-y}{{x}^{2}-{x}^{1}}m=

x

2

−x

1

y

2

−y

2 Factor out the common term yy.

m=\frac{y(y-1)}{{x}^{2}-{x}^{1}}m=

x

2

−x

1

y(y−1)

3 Use Rule of One: {x}^{1}=xx

1

=x.

m=\frac{y(y-1)}{{x}^{2}-x}m=

x

2

−x

y(y−1)

4 Factor out the common term xx.

m=\frac{y(y-1)}{x(x-1)}m=

x(x−1)

y(y−1)

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
