Question

why is 3700 = 37 x 10(squared) not in standard form?

Answer 1

Is it because has to be a single unit?

Answer 2

Because 37 has to turn into 3.7?

Answer 3

i think you want scientific notation
which mean there can be only one digit before the decimal place,
so yes make 37 into 3.7 (diving by ten), and to balance , add one to the power of ten (multiplying by ten)
