Question

Simplify : 9^3/2-3×5^0-(1/81)^-1/2 Answer ???...

Answer 1

Hello,
we have that
$9 ^{ \frac{3}{2} }-3\times 5 ^{0} -( \frac{1}{81} )^{- \frac{1}{2} }$;
so:
$=9 ^{ \frac{1}{2}\times 3 }-3\times 1-81 ^{ \frac{1}{2} }$;
$=(9 ^{ \frac{1}{2} }) ^{3}-3 - \sqrt{81}$;
$=(\sqrt{9}) ^{3} -3-9$;
$=(3) ^{3}-3 -9$;
$=27-3-9$;
$=15$

bye :-)
