 Question 1

Q1)   (3x+4) ²

      = (3x) ² + 2(3x)(4)+(4)2

      = 9x² + 24x + 16

Q2) (5x-3) ²

      = (5x) ² - 2(5x)(3)+ (3) ²

      = 25x²    - 15x + 9

Q3)  (3x-5)(3x+5)

Law Of Indices (Secondary 3 E Maths)

 

1. a^m * aⁿ = a ^(m+n).      

2. a ^(-m) = 1 / a^m.

3. a^m / aⁿ = a ^(m-n) , a > 0.

4. (a^m) ⁿ    =    a ^{(m * n)}.

5. (a * b) ^m = a^m * b^m.  

6. (a / b) ^m = a^m / b^m , b > 0.

7. a⁰ = 1.  



2³   , where 2 is the base and 3 is the power
