Write each number as a decimal.
A. 9.7 x 10^4
B. 9.88 x 10^(-4)
Question A
Positive exponent 4 tells me to move the decimal point 4 places to the right.
Doing so, I get 97,000.
Note: 97,000 = 97,000.00.
Question B
Negative exponent 4 tells me to move the decimal point 4 places to the left.
Doing so, I get 0.000988.
