What should come in place of question mark (?) in the following question ?
$$[(144)^{2}\div48\times18]\div36=\sqrt{?}$$
$$(27)^{18}\div(27)^{3}=?$$
$$5\frac{1}{4}+6\frac{2}{3}+7\frac{1}{6}=?$$
$$4895+364\times0.75-49=?$$
$$24336\div?=78\times24$$
$$156+16\times1.5-21=? $$
$$(98)^{45}\times(98)^{-35}=?$$
434.43+43.34+3.44+4+0.33=?
(23.6 % of 1254) - (16.6 % of 834)=?
