Answer:
Step-by-step explanation:
10^0=1
10^-3 = 1/10^3
4.0=4
so : 1.72×10^0/4.0×10^-3 = (1.72× 10^3)/4 =430
scientific notation is : 4.30× 10^2
5^-3 is 1/125
The negative in the exponent makes it so there is a 1 over the problem if there was no negative. When you have a negative in the exponent, the answer will be the reciprocal (opposite) of the question with no negative.
For example,
9^2 = 81
9^-2 = 1/81
I think the answer is x2 +64 but I hope you get it right good luck ! I hope it is 64 thanks
