Exercises Polynomials and factoring

Example 10.71 from Prealgebra, 10.5 Integer Exponents and Scientific Notation

Integer Exponents and Scientific Notation: example 10.71

Simplify: ${(k^{3})}^{−2} .$

Work it out on paper first. Then open the solution one step at a time, and stop as soon as you can finish on your own.

Solution

${(k^{3})}^{−2}$

Use the Product to a Power Property, ${(a b)}^{m} = a^{m} b^{m} .$ $k^{3 (−2)}$

Simplify. $k^{−6}$

Rewrite with a positive exponent. $\frac{1}{k^{6}}$

Your turn

The book's Try It right after this example: same idea, new numbers. Only the answer is given.

Simplify: ${(x^{4})}^{−1} .$
