How to add a + b using 45a +90b

yulyashka [42]

Answer:

45(a + 2b)

Step-by-step explanation:

45a

step1 in order to factor an integer, we need to repeatedly divide it by the ascending sequence of primes (2, 3, 5...) The number of times that each prime divides the original integer becomes its exponent in the final result

Prime number 3 to the power of 2 equals 9 .

Prime number 5 to the power of 1 equals 5 .

$3x^{2} *5$

90b

do the same as above

Prime number 2 to the power of 1 equals 2 .

Prime number 3 to the power of 2 equals 9 .

Prime number 5 to the power of 1 equals 5 .

$3x^{2} *5*2$

we already have 20 silver, so we need to add 120-20, that is 100 silver cars!
