c x = 10/3
log (3x) =1
take each side to 10 to the power. that will get rid of the base 10 log
10 ^(log (3x)) =10^1
3x = 10
divide by 3
3x/3 = 10/3
x = 10/3
1. by definition, scientific notation has the following form:
a is a number between 1 and 10 but does not include 10.
b an integer.
2. when you multiply 3.25 by 7.8 the result is 25.35 and when you multiply by , you obtain , but to write ree thsult in scientific notation, the decimal point must be after the first digit. therefore, you must move the decimal point one place to the left. so, the exponent changes from 9 to 10:
the correct answer is 108 cm2; 27 cm2; 135 cm2
dropped 9 of them. how many were...
