How would you expand 2.34 x 10^7 and 1.7 x 10^-12

2.34x10^7=23400000

1.7x10^12=1700000000000

the second you dropped the negative sign

1.7*10^-12= 0.000 000 000 001 7

To expand numbers written in scientific notation, you multiply the coefficient by the power of 10.

1) For 2.34 x 10^7:

- The coefficient is 2.34.
- The power of 10 is 7.
- To expand it, we multiply the coefficient by 10 raised to the power of 7:

2.34 x 10^7 = 2.34 * (10 * 10 * 10 * 10 * 10 * 10 * 10) = 23,400,000.

Therefore, 2.34 x 10^7 is equal to 23,400,000.

2) For 1.7 x 10^-12:

- The coefficient is 1.7.
- The power of 10 is -12.
- To expand it, we multiply the coefficient by 10 raised to the power of -12:

1.7 x 10^-12 = 1.7 * (1/10 * 1/10 * 1/10 * 1/10 * 1/10 * 1/10 * 1/10 * 1/10 * 1/10 * 1/10 * 1/10 * 1/10) = 0.0000000000017.

Therefore, 1.7 x 10^-12 is equal to 0.0000000000017.
