Which of the following is the simplified expression of 2 square root of -16 + the square root of 225 in standard form, a plus b

LuckyWell [14K]

Answer:

<em>The standard form like $(a+bi)$ will be: $15+8i$ </em>

Step-by-step explanation:

Given expression is: $2\sqrt{-16}+\sqrt{225}$

First factoring out -16 as (-1×16) , we will get....

$2\sqrt{-1}*\sqrt{16}+\sqrt{225}$

Now, replacing $\sqrt{-1}$ as $i$ .......

$2i\sqrt{16}+\sqrt{225}$

Finally, simplifying the radicals in the above expression, we will get......

$2i*4+15\\ \\ =15+8i$

Thus, the standard form like $(a+bi)$ will be: $15+8i$
