apply the property of negative integer exponents to rewrite 15^-38 as an expressions with posative exponents only

To rewrite 15^-38 with positive exponents only, we can apply the property of negative exponents, which states that a number raised to a negative exponent is equal to the reciprocal of the number raised to the positive exponent.

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