It would help if you proofread your questions before you posted them.

Online "^" is used to indicate and exponent, e.g., x^2 = x squared.

Online, “*” is used to indicate multiplication.

7-9. Correct.

10. There is no equation. Equation requires equal sign (=).

11. 52 * 54 = 2808 which is not < 58.

12. Correct.

13. No equation.

14. (1.8 * 10^1)(7 * 10^5) = 12.6 * 10 ^6

I won't respond to the remaining items until you get your notation correct.
