Question

А⁸b³+a⁶b⁵\a⁶b³ якщо а=0,3 , b =-0,4​

Answer 1

Ответ:

0,25

Объяснение:

a=0,3=3/10; b=-0,4=-4/10

(a⁸b³+a⁶b⁵)/(a⁶b³)=(a⁶b³(a²+b²))/(a⁶b³)=a²+b²=(3/10)²+(-4/10)²=9/100 +16/100=25/100=0,25

Answer 2

To evaluate the expression A⁸B³ + A⁶B⁵ / A⁶B³ with A = 0.3 and B = -0.4, let's substitute these values into the expression and perform the calculations.

A⁸B³ + A⁶B⁵ / A⁶B³ (0.3)⁸(-0.4)³ + (0.3)⁶(-0.4)⁵ / (0.3)⁶(-0.4)³

Now let's calculate the individual parts of the expression:

(0.3)⁸ = 0.0006561 (-0.4)³ = -0.064 (0.3)⁶ = 0.000729 (-0.4)⁵ = -0.01024

Substituting these values into the expression:

0.0006561 * (-0.064) + 0.000729 * (-0.01024) / (0.000729 * (-0.064))

Calculating the values:

-0.00004198 + (-0.00000747) / (-0.000046656) = -0.00004945 / (-0.000046656) ≈ 1.059

Therefore, when A = 0.3 and B = -0.4, the expression A⁸B³ + A⁶B⁵ / A⁶B³ evaluates to approximately 1.059.
