Question

$25exagram$ $=$_________$yottagram$

• A. $25\times {10}^{-24}$
  
• B. $25\times {10}^6$
  
• C. $25\times {10}^{24}$
  
• D. $25\times {10}^{-6}$
  

Answer 1

The correct option is D $25\times {10}^{-6}$


$1exagram={10}^{18}grams$
$25exagrams=25\times {10}^{18}grams$
$1yottagram={10}^{24}grams$
Then $25\times {10}^{18}grams$ $=\frac{25\times {10}^{18}}{{10}^{24}}=25\times {10}^{-6}yottagrams$
