• Indices Rules
• a^m × a^n = a^(m+n)
• a^m ÷ a^n = a^(m-n)
• Divide: subtract the powers
• Only when base number is the same
• a^m × a^n = a^(m+n)
• Divide: subtract the powers
• (a^m)^n =    a^mn
• When raising a power to a power: times the powers
• a^0 = 1
• a^1=a
• a^(?m) = 1/a^m
• When raising a number to a negative power: the reciprocal of the number to the power of the index.
• a^(p/q)=(q?a)^p
• Raising a number to a fraction: the denominator becomes the "root" and the numerator becomes the "power"
• a^(1/q) = q?a
