Solve 13 = d ÷ 6. The solution is d =​

d=78

Step-by-step explanation:

13= 78÷6.

How you do it is inverse operation to get your answer. For example, for this the opposite of division is multiplication so you multiply 6 by the quotien or 13 and you get d=78, to make sure it's the right answer you divide the equation getting the same answer d=78

78

Step-by-step explanation:

One simple way to solve problems like this is to multiply the number being divided in this case 6 and the end result in this case 13

so we do 6x13=78

ddd

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
