Need an real nerd to solve this points? first to answer with good explanation will get brainlest

30 *a^5  b^7  c^6

Step-by-step explanation:

(5a^2b^3c^4) (6a^3b^4c^2)

Multiply like terms

5*6   a^2a^3   b^3b^4    c^4 c^2

When we multiply exponents with the same base, we keep the base the same and add the exponents  (x^y *x^z) = x^(y+z)

30   a^(2+3)   b^(3+4)    c^(4+2)

30 *a^5  b^7  c^6

9

Step-by-step explanation: The answers 9 cus 135+5x has to equal 180 so u do 180 -135 =45 than divid 45 to 5 which equals 9
