Final answer:
No provided option correctly simplifies the expression 72x10y without additional context. Arithmetic operations or exponent rules are typically used, but the expression may already be in its simplest form as 720xy, unless further context is provided.
Step-by-step explanation:
To rewrite the expression 72x10y as simply as possible, none of the provided options a. 36x'yas b. 37'y By c. 6x*y/2y d. 9xy17/ seem to correctly simplify the given expression. Normally, arithmetic operations such as multiplication or exponent rules would be applied, but in this case, no further simplification is obvious from the given expression without additional context or information.
If the intention was to simplify the numerical coefficient and the variables independently, we would simply have the expression as it stands, 72x multiplied by 10y. However, if we were to factor out common factors, it could potentially be simplified to 720xy, assuming that 'x' and 'y' are variables and the operation between 72 and 10 is multiplication. If there are no common factors between 'x' and 'y', then the expression cannot be further simplified.
Without additional context, we cannot accurately perform further simplification or choose from the given options.
