Question

3a(a+b)2/9a2(a+b) где a=2 b=1

Answer 1

Ответ:

0.3

Объяснение:

3*2(2+1)*2:9*2*2(2+1)=6*3*2:18*6=0.3

Answer 2

To evaluate the expression 3a(a+b)^2/9a^2(a+b) with a = 2 and b = 1, we substitute the given values into the expression and simplify:

Substituting a = 2 and b = 1: 3(2)(2+1)^2 / 9(2^2)(2+1)

Simplifying the numerator: 3(2)(3)^2 / 9(4)(3)

Calculating the numerator: 3(2)(9) / 9(4)(3) 54 / 108

Simplifying the denominator: 54 / (36)(3) 54 / 108

The numerator and denominator have a common factor of 54, so we can simplify further: 1 / 2

Therefore, the expression 3a(a+b)^2/9a^2(a+b), with a = 2 and b = 1, simplifies to 1/2.
