Final answer:
The expression (-37)x(-37)x...x(-37) 101 times can be expressed in exponential notation as (-37)^101.
Correct option is A.
Step-by-step explanation:
To express the given expression in exponential notation, we need to multiply (-37) by itself 101 times. In exponential notation, the base is (-37) and the exponent is 101. Therefore, the answer is (-37)^101.
