I think its agree. I hope that helped
Step-by-step explanation:
The simplified mathematical expressions with the first factor to the nearest tenth are:
7.8 x 10
3.3 x 
2.1 x 
3.7
<h3>What are the
simplified mathematical expressions ?</h3>
Scientific notation is used to simplify large numbers in smaller numbers. In order to write a number in scientific notation , the number is written as a decimal number, between 1 and 10 and multiplied by a power of 10.
(8.6 x
) . (9.1 x
)
= (8.6 x 9.1) x
= 78.26 x
= 7.8 x 10
(6.9 x
) . (4.8 x
)
= 33.12 x 
3.3 x 
(3.7 x
) . (4.6 x
) ÷ (1.4 x
) . (5.7 x
)
= 1.7 x 10 ÷ 8 x10²
0.21 x 
2.1 x 
(3.1 x
) . (5.3 x
) ÷ (7.3 x
) . (6.1 x
) = 3.7

The greatest common factor is

EXPLANATION
We want to find the greatest common factor of

and

The prime factorizations are;

and

The product of the least powers of the common factors is the greatest common factor.
Answer:
a³ + b³
Step-by-step explanation:
Given
(a + b)(a² - ab + b²)
Each term in the second factor is multiplied by each term in the first factor, that is
a(a² - ab + b²) + b(a² - ab + b²) ← distribute both parenthesis
= a³ - a²b + ab² + a²b - ab² + b³ ← collect like terms
= a³ + b³
