Answer 1

Ответ:

128

Пошаговое объяснение:

(2b)^5÷b^9×b^5

2^5×b^5÷b^9×b^5⇒b^5-9-5⇒b^1

2^5×b при b=4

32×4=128

Answer 2

To evaluate the expression (2b)^5 / (b^9 * b^5) when b = 4, follow these steps:

Step 1: Substitute b with 4 in the expression: (2 * 4)^5 / (4^9 * 4^5)

Step 2: Simplify the numerical values: (8)^5 / (262144 * 1024)

Step 3: Calculate the powers: 32768 / 268435456

Step 4: Simplify the fraction (divide the numerator by the denominator): 0.0001220703125

So, when b = 4, the value of the expression (2b)^5 / (b^9 * b^5) is approximately 0.0001220703125.
