Fairly interesting new study, which finds, inter alia, when teachers dedicate more class time to requiring their pupils to actually practising mathematics, pupils do better in mathematics exams.
To the complete surprise of absolutely nobody.

@sonukg4india Think about the previous similar question where you can create a cubic whose roots are a,b,c and then substitute these into that cubic (three times) ‘bump’ them up by multiplying each by its respective root and add them together
@sonukg4india Can’t we just raise both by a power of 6 (since both are bigger than 1) and compare those? So 2^3 and 3^2. Therefore cube root of 3 is bigger.
