If d=3 what is the answer? 7b to the power of three + 10

199 if it's 7b^3 + 10

9271 if it's (7b) ^3 + 10

Step-by-step explanation:

You just substitute the 3 in for d. If your expression was 7b^3 + 10, then only b is being raised to 3.

So 3^3 is 27, 27*7 is 189, 189+10 is 199.

If the expression was (7b) ^3 + 10, then first you multiply 7 and 3 to get 21. Then you raise 21 to the power of 3, which is 9261. Then you add 10, which is 9271.
