Apply the property of negative integer exponents to rewrite 15^-³⁸ as an expression with positive exponents only.

Answer 1

To rewrite 15^-³⁸ with positive exponents only, we can apply the property of negative exponents which states that a^-n = 1/a^n.

Therefore, 15^-³⁸ can be rewritten as 1/15³⁸.

Answer 2

Apply the property of negative integer exponents to rewrite 9^-²⁸ as an expression with positive exponents only.

Answer 3

To rewrite 9^-²⁸ with positive exponents only, we can apply the property of negative exponents which states that a^-n = 1/a^n.

Therefore, 9^-²⁸ can be rewritten as 1/9²⁸.
