=5×9×√3
=45×√3
=45√3
(c) 1 / (1+0.07) 3
= 1/1.22
= 0.82
We must attach 1 and 0.07 below that first, which should be 1.07. After that, by entering the
power key in the calculator, we can calculate power 3 from 1.07 and the value would be
1.22. In addition, to obtain the result, we can isolate 1 with 1.22.
