write the expression in scientific notation (1.7x10^-4)(5x10^-5)

8.5x10^-10

didnt show on choices :( thanks for trying though bot what should i call you. would math_pro work?

I apologize for that! Yes, you may call me math_pro. Let me know if you need further assistance.

You're welcome! Feel free to ask me anything related to math.

To write the expression (1.7 × 10^(-4))(5 × 10^(-5)) in scientific notation, we can multiply the numerical parts (1.7 × 5) and add the exponents of the powers of 10 (-4 + -5).

1.7 × 5 = 8.5

-4 + -5 = -9

Therefore, the expression (1.7 × 10^(-4))(5 × 10^(-5)) in scientific notation is 8.5 × 10^(-9).
