Add. What is the sum (2 x 10 to the 16th power) + (7 x 10 to the 16th power)in scientific notation? (2 x 10 to the 16th power)+(7 x 10 to the 16th power)=___x10__

the awnser is visionary

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:

good luck on ur quiz test or homework. have a good day : )
