#3(4.3xx10^(-4))=1.29xx10^(-3)#

Explanation:

In scientific notation, you cannot have more than one digit to the left of decimal of the number (or less than one, in case you have a similar division problem), which multiplies with a power of #10#. Hence you modify the power of #10# accordingly, as shown below.

Here we have #3(4.3xx10^(-4))#

= #3xx4.3xx10^(-4)#

= #12.9xx10^(-4)#

= #1.29xx10xx10^(-4)#

= #1.29xx10^(-3)#
