Answer 1

`a=2;b=5;c=-20`

Explanation:

Given:

Number tree is given.

Given hint: To get a number in the square multiply the numbers in the two circles connected to it.

`a*(-4)=-8\\a=-(8)/(-4) \\a=2`

`a*b=10\\2*b=10\\b=(10)/(2) \\b=5`

`b*(-4)=c\\5*(-4)=c\\c=-20`

Therefore, final answers are:

`a=2;b=5;c=-20`
