2+2=4
the corrrect answer would be a=10.5
as 2(a)=21 in that expression a equals 10.5
i would ask a moderator or message someone else because i cant visualize it im sorry i couldnt help
if it is rounded up to the nearest ones place it will be equal to 1 and so the answer is it will be one if rounded up
in the power form???? if so reply through messag or answer i will help you
true im sorry for my answer and if it was wrong. anyway have a good day
no because only 1 can be one no decimal can be 1
hope this helps :)
