The seven laws of indices 1) aᵅ * aⁱ = aᵅ⁺ⁱ.              2) bⁿ bˣ = bⁿ⁻ˣ 3) x⁰ = 1 4) x⁻ᵅ = 1/xᵅ 5) (xᵅ)ⁿ =xᵅⁿ 6) x^1/a = a√x 7) x^a/b = b√x^a    the above laws of indices are true all non zero values of a, b ,  and x       Some examples of indices 1) 2³×2⁴ = 2³⁺⁴ =2⁷= 128 2) 3⁵÷3² = 3⁵⁻² =3³ =27 3) 100⁰ = 1 The third law says whenever the superscript is zero no matter what greater the value may be, then the answer is equal to 1. 4) 4⁻² =1/4² = 1/16  5) (2²)² = 2²*² = 2⁴ = 16 6) 6^1/4 = 4√6 7) x^3/2 = 2√x³ or ( 2√x )³       The video above shows the combination of indices laws in one question, please meet the tutor, watch it again and again for more understanding.  if you have any problem please don't hesitate to contact us.
