MARKING AS BRAINLIEST! LAST ATTEMPT! ( divisibility rules practice problems) how did I get 36 divisible by 2 , 3, 4, 6,9 ?

2x18=36

12x3=36

4x9=36

6x6=36

9x4=36

Step-by-step explanation:

All other options lead to decimals (not whole numbers)

36 ÷ 3 = 12

36 ÷2 = 18

36 ÷ 4 = 9

36 ÷ 6 =6

36 ÷ 9 = 4

Step-by-step explanation:

a.

step-by-step explanation:

step 1 distribute 2 to every term in the parentheses

step 2 add 10 on both sides of the equal sign

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
