7. Which of the following is NOT true about the expression given below? (10+4)^2-25 a. The 4 will be raised to the second power b. Subtracting 25 will be the last step c.The 10 and 4 will be added first d. 14 will be raised to the second power

The correct answer is option d. 14 will be raised to the second power.<br /><br />In the given expression $(10+4)^{2}-25$, the first step is to add 10 and 4, which gives 14. Then, the result is raised to the second power, and finally, 25 is subtracted from it.<br /><br />Therefore, option d is not true because 14 will not be raised to the second power.
