PLEASE HELP IMMEDIETLY! what is 3 1/3- 1 2/3

1 2/3

Step-by-step explanation:

3 1/3 - 1 2/3

We know that you can't subtract the numerators 1 and 2 so you have to borrow from the whole number, 3 becomes a 2, and the numerator (which is 1) becomes a 4. You need to add the denominator to the numerator to get the 4. Then 4-2 =2 which is you numerator, denominator stays the same and 201 is 1 so then its 1 2/3

greater than one

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
