1,5ab-³*6a–²b

To simplify the expression 1,5ab-³*6a–²b, we can break it down step by step:

Step 1: Simplify the exponents. -³ denotes the cube of the term, and –² denotes the square of the term.

So, (ab)^-³ = 1/(ab)^3 = 1/(a^3b^3), and (a^-²b) = 1/(a^2b).

Step 2: Multiply the terms. 1,5 * 6 = 9.

So, the simplified expression is 9/(a^3b^3) * 1/(a^2b) = 9/(a^3b^3 * a^2b) = 9/(a^5b^4).
