Writing a number in standard form simply means to express the number in its 'normal' form. Therefore, your example is written in standard form.
16 + 49 = 65
65 million = 65,000,000
Expanded Notation of 65 = (6 x 10) + (5 x 1).
6.5 x 10^7
To write 65 ten-thousandths in standard form, you would start with the decimal point. Then, you would write the digit 6 in the hundredths place, the digit 5 in the thousandths place, and fill in any remaining placeholders with zeros. Therefore, 65 ten-thousandths in standard form is 0.0065.
6.5 = 65/10; you may simplify it if you so wish.
1 trillion divided by 65 million = 15,384.6 (rounded).

The isotope notation for an element with atomic number 29 (Z=29) could be represented as follows: Cu-63 or Cu-65, where Cu is the chemical symbol for copper.
It is 65/100.
none
The isotopic notation of copper-65 is written as ( ^{65}_{29}\text{Cu} ). In this notation, 65 represents the mass number, which is the total number of protons and neutrons in the nucleus, and 29 is the atomic number, indicating the number of protons in copper. This notation helps distinguish copper-65 from other isotopes of copper, such as copper-63.
65% = 65/100 = 13/20
