You're getting to be a big boy I'm just a kid who's four

Each day I grow some more

I like exploring

I'm Caillou

So many things to do

Each day is something new

I'll share them with you

I'm Caillou

My world is turning

Changing each day

With mommy and daddy

I'm finding my way!

Growing up is not so tough

'Cept when I've had enough

But there's lots of fun stuff

I'm Caillou

Caillou

Caillou

I'm Caillou

That's me!

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
