9 times 10^4 multiplied
8 times 10^6
multiply 9 times 8 = 72
with exponents you keep the base and add the exponents.
72 times 10^10
sci notation calls for one decimal place only
7.2 times 10^11
You have your exponent right, but didn't multiply the coefficients.
(9*10^4)(8*10^6) Write the results in scientific notation
7.2*10^25
1.7*10^11
7.2*10^11
1.7*10^25
