What level is this question in the maths curriculum?
Find the value of a and b in the following question.
2 to the power of a x 5 to the power of b =200
I use prime factorization to work out 2x2x2x5x5, therefore the value of a =3 and the value of b=2
I wonder what level would you expect this sort of question in the exam? Thanks in advance.

I can't answer the question on level... we'll have to wait for a teacher to do that...
... but... it does seem pretty simple... i.e even if you don't factor it... there is an obvious 25x8 there. Factoring, given that 2 and 5 are prime, of course is the correct approach.
I'll try it out of the DCs later
