Question 84
State whether the following statement is true or false:
3√8+27=3√8+3√27
False We have, 3√8+27≠3√8+3√27 [∵3√8+3√27=3√2×2×2+3√3×3×3=2+3=5] But, 3√8+27=3√35≠3√125=5
State whether the statement is True or False.
(−20)×(5−3)=(−20)×(−2)
Question 16
State whether the given statements are true (T) or false (F).
38=1540
State whether the statement is true or false. Dividing x(3x2−27) by 3(x−3) gives x2+3x.
