Express 18k³ ÷ 3k³.

To simplify the expression 18k³ ÷ 3k³, divide the coefficients and subtract the exponents of the variables:

18k³ ÷ 3k³ = (18 ÷ 3) * (k³ ÷ k³) = 6 * 1 = 6

Therefore, the simplified expression is 6.

To express 18k³ ÷ 3k³, you need to divide the coefficients and subtract the exponents.

Dividing 18 by 3 gives you 6.

Subtracting the exponents, k³ ÷ k³ is equal to k^(3-3) which simplifies to k^0.

Any number raised to the power of 0 is equal to 1.

Therefore, 18k³ ÷ 3k³ simplifies to 6.
