When finding a conjugate, and the sign is negative you change it positive and when is positive you change it to negative 👍👍👍

@@SkanCityAcademy_SirJohn Sir why do you cancel the denominator part of +10(√5√2)-10(√5√2) why can't you just make full calculations of it jus like the numerator side ...... If you can divide those then I think you will have to do the same to the numerator

@SkanCityAcademy_SirJohn 2 ай бұрын

@Pastor_Moore001 because they cancel out, okay. And that's the right....

@Pastor_Moore001 2 ай бұрын

@@SkanCityAcademy_SirJohn yes I know but you should have make full calculations of it and it will still be the same thing like saying +10-10(√5√2)(√5√2) then we will later cancel them off because they are same with no whole number holding them......

When the expression was :70 +20 root 10 all on 30 and how did you cancel the 2 0s at the numerator when the denominator is 30 with only one 0 ?

@SkanCityAcademy_SirJohn 10 ай бұрын

You factor out 10 both at the numerator and denominator. So it becomes 10(7+2sqrt(10)) / 10(30 10 cancels out 10

Can you explain how did you factor out the zeros in the last step ?

@SkanCityAcademy_SirJohn 7 ай бұрын

you have (70 + 20 root (10))/ -30 = 10/10 * (7 + 2(root 10))/-3

I fully agree with social sir cause simply even in this video kzbin.info/www/bejne/jKHKg317l72XbK8 that you made the conjugate sign changes both in num and denominator with the same sign

@SkanCityAcademy_SirJohn Жыл бұрын

Are you aware that anytime you want to rationalize a surd you multiply both num and deno by conjugate of the denominator?

The denominator is still negative 3. Just that we have represented in a more nicer way, leaving -1 outside the bracket. It's still the same thing
