Estimate 306.9 divided by 6.4

48.

Step-by-step explanation:

Given  :  306.9 divided by 6.4

To find : Estimate

Solution : We have given 306.9 divided by 6.4

We can write it as

On removing decimal of both number

.

We get 47.95

After decimal number is 9 which is greater than g os it would be rounded up 48.

Therefore, 48.

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
