Answer:

$→\sqrt{ - 16} + \sqrt{49}$

We know that, i = √-1
Form → a + ib

$→( \sqrt{ - 1} \times \sqrt{16} ) + ( \sqrt{49} )\\=i \sqrt{16}+\sqrt{49} \\ = 4i + 7 \\ = \boxed{7 + 4i}✓$

(7 + 4i) is the right answer.

Simplify. 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

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