A) (357,911)
B) (250,731)
C) (405,224)
D) (318,276)

Answer 1

To find the value of (71³) using the shortcut method, find the cube of the last digit and the square of the remaining part of the number, then combine the results.

Step-by-step explanation:

To find the value of (71³) using the shortcut method, you can follow these steps:

1. Start by finding the cube of the last digit, which is 1. 1³ = 1.
2. Next, find the square of the remaining part of the number, which is 7. 7² = 49.
3. Finally, combine the results from steps 1 and 2 to get the final value. In this case, it would be 1 followed by 49, so the value of (71³) is 7149.
