The Laws of indices :The Laws of indices :
#1: The exponent of a power indicates how many times the base multiplies itself.

#2: Multiplying Powers: If you are multiplying Powers with the same base, KEEP the BASE & ADD the EXPONENTS!
m n m nx x x
So, I get it! When you multiply Powers, you add the exponents!

#3: Dividing Powers: When dividing Powers with the same base, KEEP the BASE & SUBTRACT the EXPONENTS!

#4: Power of a Power: If you are raising a Power to an exponent, you multiply the exponents!
nm mnx x
So, when I take a Power to a power, I multiply the exponents

#5: Product Law of Exponents: If the product of the bases is powered by the same exponent, then the result is a multiplication of individual factors of the product, each powered by the given exponent.
n n nxy x y So, when I take a Power of a Product, I apply the exponent to all factors of the product.

#6: Quotient Law of Exponents: If the quotient of the bases is powered by the same exponent, then the result is both numerator and denominator , each powered by the given exponent.
n n
n
x x
y y
So, when I take a Power of a Quotient, I apply the exponent to all parts of the quotient.

#7: Negative Law of Exponents: If the base is powered by the negative exponent, then the base becomes reciprocal with the positive exponent.
1mm
xx
So, when I have a Negative Exponent, I switch the base to its reciprocal with a Positive Exponent.
Ha Ha!
If the base with the negative exponent is in the denominator, it moves to the numerator to lose its negative sign!

So zero factors of a base equals 1. That makes sense! Every power has a coefficient of 1.
