Answer:
Step-by-step explanation:
The associative property never works with subtraction.
For example:
2 - (7-8) <span>≠ (2-7) - 8
2-(-1)=3, but (-5)-8=-13
</span>
Step-by-step explanation:
after rationalising we get as b)19
multiply 3√3+2√2 on numerator and denominator
7(3√3+2√2)/(3²*3-2²*2)
7(3√3+2√2)/27-8
7(3√3+2√2)/19
so denominator is 19
