Ok, again folks I am asking for your help!! I have managed to do the rest of the 100 questions but I am totally stuck on these ones (after I managed to get some great help on my other topic, thank you!)
I need whatever is in brackets, to be the subject.
(sq) = squared or whatever the value is
Q1. v(sq) = 2gh (h)
Q2. v = 5a
a - b (b)
Q3. c = [square root over this whole equation]2hr - h(sq) (r)
Now these ones are simplifying again...
Q1. a(sq) x a(3rd) x a(-5)
Q2. [square root] 9a(4)b(sq)
Q3. [square root] X(3rd) x X(5)
Thank you very much for all your help!!
to Q1.: The bases of all powers are the same therefore you only have to add the exponents:
to Q 2.: I've some trouble to read your problem. Therefore I'll offer you 2 different ways to this problem. You have to decide which result is the right one!
to Q 3.: Same procedure as the last question:
