Which expression is equivalent to 15a^8b^4/5a^4b

LekaFEV [45]

Answer: The given expression $\frac{15a^8b^4}{5a^4b}$ simplified to $3a^4b^3$

Step-by-step explanation:

Given : expression $\frac{15a^8b^4}{5a^4b}$

We have to simplify the given expression $\frac{15a^8b^4}{5a^4b}$

Consider the given expression $\frac{15a^8b^4}{5a^4b}$

Divide the numbers $\frac{15}{5}=3$

$=\frac{3a^8b^4}{a^4b}$

Apply exponent rule, $\frac{x^a}{x^b}\:=\:x^{a-b}$

We have,

$\frac{a^8}{a^4}=a^{8-4}=a^4$

$=\frac{3a^4b^4}{b}$

Cancel out common factor b,

We have

$=3a^4b^3$

Thus, the given expression $\frac{15a^8b^4}{5a^4b}$ simplified to $3a^4b^3$

What is the simplified form of the expression (6^-4)^-9/6^6?

aleksley [76]

Answer:

$(\frac{1}{1296} )^{\frac{729}{64} }$

Step-by-step explanation:

I am assuming this problem reads $(6^{-4}) ^{-\frac{9}{6}^6 }$

So let's start on the outside and work our way towards the middle
Starting with the $(-\frac{9}{6} )^{6}$ , this can be simplified to $\frac{729}{64}$

Now we have $(6^{-4})^\frac{729}{64}$

Now simplifying what is inside the parenthesis we get $\frac{1}{1296}$
Combining what we have the simplified for of the problem becomes: $(\frac{1}{1296} )^{\frac{729}{64} }$

If order matters, then there are 12 ways to do this

If order does not matter, then there are 6 ways to do this

===========================================

We have 4 choices for the first slot and 3 choices for the next (we can't reuse a letter) so that's where 4*3 = 12 comes from

If order doesn't matter, then something like AB is the same as BA. So we are doubly counting each possible combo. To fix this, we divide by 2: 12/2 = 6

To be more formal, you can use nPr and nCr to get 12 and 6 respectively (use n = 4 and r = 2)
