Apply the Property of Negative Integer Exponents to rewrite 15−38 as an expression with positive exponents only.

To apply the property of negative integer exponents, we use the fact that any non-zero number raised to a negative exponent is equal to the reciprocal of that number raised to the positive exponent.

Therefore, we can rewrite 15^(-38) as 1 / (15^38).

To apply the property of negative integer exponents, we can use the rule:

a^(-n) = 1 / a^n

Apply this rule to rewrite 15^(-38) as an expression with positive exponents:

15^(-38) = 1 / 15^(38)

Therefore, 15^(-38) can be expressed as 1 divided by 15 raised to the power of 38.

To apply the property of negative integer exponents, we can use the following rule:

a^(-n) = 1 / (a^n)

Now, let's rewrite 15^(-38) using this property:

15^(-38) = 1 / (15^38)

So, the expression with positive exponents only is 1 / (15^38).
