Answer:
1.21 * 10^5
Step-by-step explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10.
If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
121, 000
Let 121,000 = 1.21 by moving the decimal point 5 units to the left.
Moving to the left creates a positive power.
Multiply by 10.
1.21 x 10^5
