no they are different
if Base are equal power are added
like wise in first expressions power are added
but in second expressions cube of three is written as x to the power.
so they are not equal
60 + 90
GCF = 30
(30 * 2) + (30 * 3) = 30(2 + 3) <== the correct way
The mistake Axial made was he did not pick the greatest common factor...he picked 3 instead of 30.
All numbers that are 0._ are _/10 therefore that would be 9/10 because this ratio cannot be simplified further.
I think the answer is C not to sure
