(6.496×10^−6)÷(2.8×10^5)

Express your answer in scientific notation.

=(6.496x10^-6)x10^-5/2.8

=6.496/2.8 x10^-6 x10^-5

= 2.32 x 10^(-6-5)

=2.32 x10^-11

=2.32/10^11

well the answer to that is xoxoxo

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
