Answer:

72 adults

22 children

Step-by-step explanation:

Let c = no. of children

a = no. of adults

Then 4c = total sales for the children and

7a = total sales for the adults

So, a + c = 94 and 7a + 4c = 592

-4a - 4c = -376

3a = 216

a = 72 adults

72 + c = 94

c = 22 children

trasher [3.6K]

Answer: $n^{9}$

Step-by-step explanation:

Given expression: $n^6\cdot n^5\div n^4\cdot n^3\div n^2\cdot n$

The law of exponents are given by :_

$a^m\cdot a^n=a^{m+n}\\\\a^m\div a^n=a^{m-n}$

Using PEDMAS, first we solve division, we get

$n^6\cdot n^{5-4}\cdot n^{3-2}\cdot n\\\\=n^6\cdot n\cdot n\cdot n$

Now, using product law of exponent we get

$n^{6+1+1+1}\\\\=n^{9}$
