Question

6,98а - а^2 при а = 1, 98​

Answer 1

Ответ:

Объяснение:

$\[6,98a-{a^2}=a\cdot (6,98-a)\]$

Подставим значение а = 1,98​

$\[1,98 \cdot (6,98-1,98)=1,98 \cdot 5=\boxed{9,9}\]$

Answer 2

To evaluate the expression 6.98a - a^2 when a = 1.98, we substitute the value of a into the expression and perform the calculations:

6.98(1.98) - (1.98)^2

= 13.802 - 3.9204

= 9.8816

Therefore, when a = 1.98, the value of the expression 6.98a - a^2 is 9.8816.
