$200 \text{ trillion } = 200 \times {10}^{12} = 2 \times {10}^{14}$

#### Explanation:

Names are given to numbers according to the number of placeholders, which are power of 10.

$\text{quadrillion} = 1 , 000 , 000 , 000 , 000 , 000 = 1 \times {10}^{15}$
$\text{trillion} = 1 , 000 , 000 , 000 , 000 = 1 \times {10}^{12}$
$\text{billion} = 1 , 000 , 000 , 000 = 1 \times {10}^{9}$
$\text{million} = 1 , 000 , 000 = 1 \times {10}^{6}$
$\text{thousand} = 1 , 000 = 1 \times {10}^{3}$
$\text{HTU}$

Therefore: $200 \text{ trillion } = 200 \times {10}^{12}$

In scientific notation= $2 \times {10}^{14}$
