1.45*100 but the exponent of 10 is unnecessary.
0.00001207 = 1.207E-5
3.5 x 108 = 350,000,000
Convert each item to standard form before addition. To convert scientific form to standard form move the decimal point the number of digits given by the exponent, if positive to the right, if negative to the left; if the digits run out insert zeros. If no decimal point is visible it is "hiding" after the last digit. 8 x 10¹ = 80 3 × 10^-3 = 0.003 → 8 × 10¹ + 3 × 10^-3 = 80 + 0.003 = 80.003
5.75 × 109 written in regular notation is 5,750,000,000
4.53*10-6 0.00000453 is in standard notation just move the decimal place over how ever many times the exponent is on the 10
23 000. This is standard form and should be written as: 23 x 10^2. (The ^ denotes an exponent.)

You write 1 to the 10th power (1 exponent: 1/10

The result of 56 over 196 in standard form is 2.857143 × 10-1
I believe it is: 3.02•10^5 (^5 means five as an exponent to 10. Can't make the 5 smaller)
