Question

Write 0.1234 in standard form.

• A. It's already in standard form
• B. $1.234\times {10}^{-1}$
• C. $12.34\times {10}^{-2}$
• D. $1234\times {10}^{-4}$

Answer 1

The correct option is B

$1.234\times {10}^{-1}$

In standard form, any number is expressed in powers of 10. The decimal number must be in between 1 and 10.

$0.1234=\frac{1.234}{10}=1.234\times {10}^{-1}$
