hi i'm stuck on a mathematics question where i'm supposed to be finding the values of each of these square roots to sum up with a number rounded by 1 decimal...?
i've always failed in mathematics for a while so i was wondering if i could get some help?
Use your calculator to find the values of these square roots.
Round each answer to 1 decimal place.
a 15 =
b 20 =
c 26 =
d 30 =
e 42 =
f 70 =
g 125 =
h 150 =
i 200 =
Surely you can push the buttons on your calculator
e.g.
e) √42
on my scientific calculator I press
√
42
=
and I get 6.4807...
since you want only 1 decimal place
√42 = appr 6.5
on some calculators, you have to enter the number first, then press √
just experiment with yours to see how it works
