Answer 2

Given data: $a=3\sqrt{7},b=\sqrt{7}$.

To find: The subtraction of two numbers.

Solution:

• Subtraction is defined as the difference between two numbers.
• According to the mathematic rule, The given values $a=3\sqrt{7}$ and $b=\sqrt{7}$ are subtracted ($a-b=c$ ).
• $3\sqrt{7}- \sqrt{7}=2\sqrt{7}$.
• In this case the base value$\sqrt{7}$ will be same and the difference 3 and 1 will be 2.
• Hence the subtraction of given two numbers are $2\sqrt{7}$.
