Multiply (2.5 x 10 ^-8) ( 9x10 ^ - 10 ) express answer in scientific notation

when you multiply scientific notation numbers add the exponents ( -8 + -10 = -18)

 now multiply 2.5 *9 = 22.5

 so you now have 22.5x10^-18

now make 22.5 a real scientific number by moving the decimal point 1 place to the right, which subtracts 1 from the exponent

 so you get:

2.25x10^-17

25

step-by-step explanation:

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints
