Find the value of C

Question

If A=10 and B=15 find the value of C if; A = BCsquared

Answer 1

A=BC^2, A=10, B=15

then

10=15C^2

C^2 = 10/15= 2/3

C = sqr(2/3) = (sqr6)/3 about 0.8165

Or if you by chance you meant for the problem to read

A=(BC)^2 instead of A=BC^2, then

10 =(15C)^2 = 225C^2

C^2 = 10/225 = 2/45

C = sqr(2/45) = (sqr90)/45 = about 0.2101

But PEMDAS, order of operations requires doing E before M, exponents before multiplication,

C^2 before BC, so the first answer appears correct, given the way the problem was written
