Select all of the following expressions that are equivalent to 0.36.
(0.6)2
(-0.3) + (-0.06)
|-3 + 2.64|
.36)
2x - 0.64x

The expression 0.36 is equivalent to -(-36) and |-3 + 2.64|.

Step-by-step explanation:

As the expression given in the question be

= 0.36

Take

= |-3 + 2.64 |

= | -0.36|

= 0.36

This is equivalent to 0.36 .

Take

= - (-0.36)

= 0.36

This is equivalent to 0.36 .

i'm pretty sure it's 477,585,296, but perhaps my math is incorrect.

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
