What is 5.704 expressed to two decimal places?

5.704 to two decimal places

Two Decimal Places Rule #1: If the last digit in 5.704 is less than 5, then remove the last digit. Two Decimal Places Rule #2: If the last digit in 5.704 is 5 or more and the second to the last digit in 5.704 is less than 9, then remove the last digit and add 1 to the second to the last digit.

Step-by-step explanation:

5.70, or 5.7.

Step-by-step explanation:

4 is rounded to 70 (4 and below you round down), the 5 stays the same, and then you get 5.70 which you can reduce to 5.7.

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
