Question

(4a³b)³: (2a²b²). При a=3 b=1

Answer 1

Просто подставь где а 3 и где б 1

(4+3³+1)³:(2+3²+1²)

(4+27+1)³:(2+9+1)

32³:12

$\frac{32^{3} }{12}$

$\frac{32768}{12}$

$\frac{8192}{3}$

Answer 2

To evaluate the expression (4a³b)³ / (2a²b²) when a = 3 and b = 1, we substitute the values into the expression and simplify:

Let's start with the numerator, (4a³b)³:

(4a³b)³ = (4(3)³(1))³ = (4(27)(1))³ = (108)³ = 108 * 108 * 108 = 1,244,352

Now let's move on to the denominator, (2a²b²):

(2a²b²) = (2(3)²(1)²) = (2(9)(1)) = (2)(9) = 18

Finally, we can calculate the entire expression:

(4a³b)³ / (2a²b²) = 1,244,352 / 18 = 69,131.5556

Therefore, when a = 3 and b = 1, the expression (4a³b)³ / (2a²b²) evaluates to approximately 69,131.5556.
