Divide the larger decimal number value by the smaller decimal number value.
When dividing scientific notation, divide the decimal numbers first:
2.3/1.7 = 1.3529
Now divide the exponents:
10^-3 / 10^-4
Using the law of exponents, when you divide two exponents together you subtract the exponent in the denominator from the exponent in the numerator:
-3 - -4 = -3 +4 = 1
Now combine it to get:
1.3529 x 10^1
Now convert to standard form by moving the decimal one place t the right:
13.529
Round to 13.5
