Week 3 – Math 10 – Scientific notation

This week I learned to do scientific notation which is a form of writing big numbers in smaller this can be done by moving the decimal point in your number until there is only one non-zero number this number is the base. the coefficient is always 10 to the power of the number of times you moved to the right or left this is the exponent. if you moved to the right the power is positive and to the left it’s negative. To show the scientific form we show the base we found is multiplied by ten with the exponent found. An example of this is 370000= 3.700 then since we moved to the left 4 times it’s positive and then the scientific form is 3.7 x 10^4 the expanded form is 3.7 x 10 x 10 x 10 x 10 which is the scientific form without exponents and 370000 is the standard form. Another example of scientific notation we can show is from this number  0.000087 so first we moved the decimal point to the right 5 times so the base is 8.7 which we multiple by 10 to the power of 5 where we write 8.7 x 10^-5 the other form of this number is expanded with is 8.7 x 0.00001 the standard form is 0.o00087
