[olliehancock]

Thank you, the formula substitution and formation is so much clearer

[ahmedmustafa]

Great video. Very useful especially the last one. 👍👍👍👍

[lisasaad]

[mrd]

On the last question could you take the square root 400 to give 20/6xsquared that simplifies to 10/3xsquared? And thank you for all your incredible videos. Hands down the best GCSE Maths channel on YouTube.

14:30 If I rationalised the denominator afterwards would I still get the mark?

[nads]

For the first question would -7.5 be accepted?

[JustNeutral]

Ive got a question I still need help with!

y is inversely proportional to x^2 .
It is given that y = 7 for a particular value of x.
Find the value of y when this value of x is increased by 250%.

[zgamer]

can someone explain why the formula is y=k/x(power2) when i searched up the formula for inverse proportion it does not say anything about the power 2

[Masowe.]

thank you sir, i did not know these questions exist in a way that i can answer

[khadija]

there's a reason this has no dislikes

[GCSEALevelMaths]
