4 0

Step-by-step explanation:

t = 20n + 15

t = 80

80 = 20n + 15

65 = 20n

n = 65/20 = 13/4 = 3.25 hours

Simplify.<br><br> n 6 · n 5 ÷ n 4 · n 3 ÷ n 2 · n

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

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