43÷5 with work shown please

8.6 or 8 3/5

Step-by-step explanation:

43/5

you really can't show work for this, but you can do 40/5 which is 8. then the 3/5 which is three fifths. If you need a decimal it's .6

your answer is 8.6 or 8 and 3/5

8.6

so i put then like this 45 and then i 3x5=15 and then 4x5=20 and then 20-15=5

but estumate and then 8.6                                      5

relating to or denoting a system of numbers and arithmetic based on the number ten, tenth parts, and powers of ten.

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
