Final answer:
The standard notation for 5.65 x 10° is 5.65, because any number raised to the power of 0 is 1.
Step-by-step explanation:
The proper standard notation for 5.65 x 10° is simply 5.65. In scientific notation, the expression 5.65 x 10° indicates that the decimal number 5.65 is to be multiplied by 10 raised to the power of 0. Since any number raised to the power of 0 is 1, this effectively means the number remains unchanged. So, the standard notation is the number itself, without the multiplication by ten.
