Answer:
188,418
Step-by-step explanation:
PEMDAS
multiply first
1*2=2
3*4=12
5*6=30
now we have
2+12+30=44
add
2+12=14
14+30=44
44=44
true
Here, Mass of one specimen = 0.00063 = 6.3 * 10⁻⁴
Now, Mass of 6 specimens = 6.3 * 10⁻⁴ * 6
= 37.8 * 10⁻⁴ = 3.78 * 10⁻³
In short, Your Answer would be: 3.78 * 10⁻³ Kg
Hope this helps!
(24,-21) if you multiply x by x and y by y you will get that answer
