To find : The value of the expression ?

Solution :

Expression $(81)^{\frac{1}{2}}$

We can write 81 as $81=9\times 9=9^2$

So, $(81)^{\frac{1}{2}}=(9^2)^{\frac{1}{2}}$

We know, $(a^b)^c=a^{bc}$

$(81)^{\frac{1}{2}}=9^{\frac{2}{2}}$

$(81)^{\frac{1}{2}}=9^{1}$

$(81)^{\frac{1}{2}}=9$

Therefore, the value of the expression is $(81)^{\frac{1}{2}}=9$
