ICSE Class 9 Maths Expansions Using Cubic Identities
- there is no live class in topper
- If (4a+3b)=10 and ab = 2 find the value of (64a^3 + 27b^3)
- Can U Repeat Formula For Expansions
- a^3+b^3
- solve
- I did not understood how to solve
- How to solve: If x+y+z=0, find the value of : (y+z)^2/yz+(z+x)^2/zx+(x+y)^2/xy
- if X+1/X=√3 prove that x^3+1/x^3= 0
- If a+b+2c=0 , prove that a³+b³+8c³=6abc
- If x>0 and (x^2)+(1/(9x^2))=25/36 find (x^3)+(1/27x^3)
