Webb8 dec. 2024 · In brief, you add the exponents together when multiplying and subtract one from the other when dividing, provided they have the same base. TL;DR (Too Long; Didn't Read) Multiply terms with exponents using the general rule: xa + xb = x ( a + b ) And divide terms with exponents using the rule: xa ÷ xb = x ( a – b ) WebbFor exponents with the same base, we can add the exponents: a -n ⋅ a -m = a -(n+m) = 1 / a n+m Example: 2 -3 ⋅ 2 -4 = 2 - (3+4) = 2 -7 = 1 / 2 7 = 1 / (2⋅2⋅2⋅2⋅2⋅2⋅2) = 1 / 128 = 0.0078125 When the bases are diffenrent and the exponents of a and b are the same, we can multiply a and b first: a -n ⋅ b -n = ( a ⋅ b) -n Example:
