A.
Draw arcs of equal lengths intersecting , , and in two points each.
B.
Draw the perpendicular bisectors of , , and that pass through point D.
C.
Label a point E on and draw a line joining E with D.
D.
Draw a line through D that is perpendicular to one of the sides, , , or .
E.
Draw one arc each on and , and find their point of inters

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

answer: i think you should do the math and pay attention in class : )
