Final answer:
To write the expression 1x7x7x7x7x7 using an exponent, we can use the rule that states that when we multiply the same base number multiple times, we can write it using an exponent. The expression 1x7x7x7x7x7 is equal to 7^5.
Step-by-step explanation:
To write the expression 1x7x7x7x7x7 using an exponent, we can use the rule that states that when we multiply the same base number multiple times, we can write it using an exponent. The base number in this case is 7, and since we have 5 occurrences of 7 being multiplied, we can write it as 7^5. So, the expression 1x7x7x7x7x7 is equal to 7^5.
