The subtraction of the expression 10√27 - 4√12 is 22√3.
Combining things and counting them as one big group is done through addition. In math, addition is the process of adding two or more integers together.
In mathematics, subtraction involves removing anything from a group or a number of objects. What is left in the group gets smaller when you subtract.
Consider the expression,
y = 3√20x + 8√45x - 4√5x
Now, the number in the root can also be written as:
20 = 2 × 2 × 5
45 = 5 × 3 × 3
Therefore,
y = 3√20x + 8√45x - 4√5x
y = 3( √[2 × 2 × 5] )x + 8( √[5 × 3 × 3] )x - 4√5x
y = 3 × 2√5x + 8 × 3√5x - 4√5x
y = √5x ( 3 × 2 + 8 × 3 - 4 )
y = √5x ( 6 + 24 - 4 )
y = 26√5x
The value of the expression 3√20x + 8√45x -4√5x is 26√5x.
