1 answer

To express the number 0.0000115741 in scientific notation, you can rewrite it in the form of \( a \times 10^n \), where \( 1 \leq a < 10 \) and \( n \) is an integer.

  1. Move the decimal point to the right until there is only one non-zero digit to the left of the decimal. In this case, moving the decimal 4 places to the right gives us 1.15741.

  2. Since we moved the decimal point 4 places to the right, we need to multiply by \( 10^{-4} \) to balance the equation.

Putting this together, we get:

\[ 0.0000115741 = 1.15741 \times 10^{-5} \]

So, in scientific notation, \( 0.0000115741 \) is approximately \( 1.15741 \times 10^{-5} \).
