TASK 1
(a) 1.88
In the calculator first we enter 1.8 and then will use power button by entering power 8 of
1.8. After that we click on equal button to measure the value.
110.19
(b) 5√243
(c) 1 / (1+0.07) 3
Under this first we will add 1 and 0.07 that will be of 1.07. After this we will measure
power 3 of 1.07 by entering power button in calculator and value will be of 1.22. Further,
we will divide 1 from 1.22 to get the answer.
= 1/1.22
= 0.82
(d) 2500 x 5-3
Under this, first we will compute value of 5-3 by entering number 5 in calculator and
measuring power -3. By which we will get 0.008 and this value will be multiplied to
reach the answer.
=2500*0.008
=20
(e) 34.18 + √79/ 0.4375−2.28
First of all we will find under root value of 79 by entering root button in calculator. The
value will be 8.89 and it will add in 34.18, it will be of 43.07. After this we will subtract
0.4375 from 2.28 and value will be -1.84. In the end we will enter, 43.07 and divide it by
-1.84 to get the answer.
34.18+8.89/-1.84
= -23.40
