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

Answer 1

To apply the property of negative integer exponents, we can rewrite 15^-38 as its reciprocal with the exponent changed to a positive number.

The property states that for any nonzero number "a" and integer "n", a^(-n) = 1/a^n.

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