What is the simplest radical form of 45?

For this question I'm just going to use / as a square root sign because I don't know how to do it on a computer. Anyways...

So you have /45

Now you have to find a factor that is also a perfect square which is 9 (because 9x5=45)

So you now have /9x5

Since 9 is a perfect square (/9=3)

You can re write it is 3/5 which is the answer

Explain how you know what number is missing in the equation 3,947 = 3,000 + Blank + 40 + 7

sashaice [31]

It's in expanded form, so you add each part (thousands, hundreds, tens, and ones) separately. the hundreds is missing. looking at the number, it is 900.

–4.5t49.5t = 40<br> Please help

dlinn [17]

Answer:

t= -0.18

Step-by-step explanation:

Isolate t to get the unknown number:

(-4.5t)(49.5t) = 40

Multiply (-4.5t)(49.5t):

(-4.5t)(49.5t) = -222.75t

Now, write full equation:

-222.75t = 40

Isolate t by dividing -222.75 on both sides:

$\frac{-222.75}{-222.75}t=\frac{40}{-222.75}$

Cancel out left hand side:

$t=\frac{40}{-222.75}$

Simplify your answer:

$t=-0.17957351$

Approximate to 2 decimals:

$t=-0.18$

If log a = x and log b = y, then log (ab2) equals

mylen [45]

Answer:

The answer for log(ab²) is x + 2y.

Step-by-step explanation:

You have to apply Logarithm Law,

$log(a) + log(b) \: ⇒ \: log(a \times b)$

$log( {a}^{n} ) \: ⇒ \: n log(a)$

In this question, you have to seperate it out :

$log(a {b}^{2} ) = log(a) + log( {b}^{2} )$

$log( {b}^{2} ) = 2 log(b)$

$let \: log(a) = x$

$let log(b) = y$

$log(a {b}^{2} ) = log(a) + 2 log(b)$

$log(a {b}^{2} ) = x + 2y$
