1(10^3)^6

To solve this expression, we can simplify it step by step:

1. First, we simplify the exponent within the parentheses:
(10^3)^6 = 10^(3*6) = 10^18

2. Now, we can simplify the remaining expression:
1 * 10^18 = 10^18

Therefore, 1(10^3)^6 is equal to 10^18.

To simplify the expression 1(10^3)^6, we need to follow the order of operations, which is parentheses first, then exponents.

Step 1: Evaluate the exponent inside the parentheses.
10^3 = 10 * 10 * 10 = 1,000

After simplifying the exponent, the expression becomes:
1(1,000)^6

Step 2: Evaluate the exponent outside the parentheses.
(1,000)^6 = 1,000 * 1,000 * 1,000 * 1,000 * 1,000 * 1,000 = 1,000,000,000,000,000,000,000

Therefore, the answer to the expression 1(10^3)^6 is 1,000,000,000,000,000,000,000.
