1, 81, and 121 are perfect squares.

1x1=1, so it is technically a perfect square. 81 is a perfect square because 9 can be multiplied by 9 to get 81. 121 is a perfect square for the same reason- 11 can be multiplied by itself to get 121

Answer:

x = (√6)/10^0.7 ≈ 0.488737

Step-by-step explanation:

It can work reasonably well to take antilogs first.

$\log(6)-2\log(x)=1.4\\\\\dfrac{6}{x^2}=10^{1.4}\\\\\dfrac{6}{10^{1.4}}=x^2\\\\x=\dfrac{\sqrt{6}}{10^{0.7}}\approx0.488737$
