Final answer:
The expression '-13 x ... x -13' repeated 10 times is represented in exponential notation as '(-13)^10', where '-13' is the base and '10' is the exponent indicating repetition.
Step-by-step explanation:
Expressing the repetition of multiplying -13 by itself 10 times in exponential notation means using a base of -13 raised to a power that represents the number of times it is multiplied.
Written in exponential form, it is (-13)^10.
Exponential notation simplifies the expression of repeated multiplication, making it much easier to read and work with, especially with larger numbers.
In this case, the base is the repeated factor (-13) and the exponent (10) indicates how many times that base is used as a factor in the multiplication.
