Answer 1

Ответ:

(9-10×0,3)(81+90×0,3+100×0.3^2)=(9-3)(81+27+9)=6×117=702

Answer 2

Solution for (9-10x)(81+90x+100x^2) when x=0.3

To solve the given expression for the value of x=0.3, we can simply substitute the value of x into the expression and perform the calculations.

Substitute x=0.3 into the expression (9-10x)(81+90x+100x^2):

(9-10*0.3)(81+90*0.3+100*0.3^2)

Now, let's calculate the expression step by step.

First, calculate the values inside the parentheses:

(9-3)(81+27+9)

6 * 117

702

So, the value of the expression (9-10x)(81+90x+100x^2) when x=0.3 is 702.

This calculation can also be verified using the distributive property of multiplication, which yields the same result.

Answer: 702
