Answer 2

Note: Question should be like this,

$\[{10^{ - 3}} \times {10^{ - 4}}\]$ का मान क्या होगा?

$\[\begin{array}{l}\left( a \right){10^{ - 12}}\\\left( b \right){10^{12}}\\\left( c \right){10^{ - 7}}\\\left( d \right){10^7}\end{array}\]$

Given,

$\[{10^{ - 3}} \times {10^{ - 4}}\]$

Solution,

$\[\begin{array}{l} = {10^{ - 3}} \times {10^{ - 4}}\\ = {10^{ - 3 - 4}}\\ = {10^{ - 7}}\end{array}\]$

Hence the value is $\[{10^{ - 7}}\]$

The correct option is (c), i.e. $\[{10^{ - 7}}\]$
