Question 99·200 Super-Hard SAT Math Questions·Advanced Math
For the exponential function , the value of is , where is a constant. Which choice gives an equivalent form of that shows the value of as the coefficient or the base? ЅАT рrep by Aniкο.ai
When an exponent has a denominator (like ), rewrite the base using prime powers so the denominator cancels cleanly (here, ). Next, compute the given reference value . Finally, rewrite each exponential factor so it is expressed in terms of ; the leftover constants multiply to , making appear explicitly as the coefficient. (Аnіko.ai)
Hints
Factor the base
Rewrite as a product of powers, like . Anіko - Frеe SAT Рrеp
Use exponent rules to split factors
Apply and to simplify .
Pull out the part at
Try rewriting as and as so the coefficient becomes .
Desmos Guide
Enter the original function
In Desmos, enter From anіkо.ai
(use parentheses around ).
Find from a table
Add a table for the expression and enter . The corresponding -value is .
Test the answer choices
Enter each answer choice as another function (for example, ). The correct choice will match the original graph exactly and will show as the coefficient.
Step-by-step Explanation
Rewrite 96 using prime powers
Factor as and apply exponent rules:
So
Compute
Substitute :
Rewrite in terms of
Rewrite each factor so the part corresponding to is separated:
Make the coefficient
Substitute these into and combine constants:
Therefore, the correct choice is .
