Answer 2

To solve the expression given, we'll substitute the values of a = 1 and b = -1 into the equation. Let's break it down step by step:

Expression: -9,4a25b9 : a® — 0,6a10 . (а"b9)

Step 1: Substitute the values a = 1 and b = -1 into the expression.

-9,4(1)25(-1)9 : 1® — 0,6(1)10 . (1"(-1)9)

Step 2: Simplify the expression by performing the operations in order.

-9,4(1)(25)(-1)(9) : 1® — 0,6(1)(10) . (1"(-1)(9))

Step 3: Continue simplifying the expression.

-9,4(-25)(-9) : 1® — 0,6(10) . (1 + 9)

Step 4: Simplify further.

-9,4(225) : 1® — 6 . (10)

Step 5: Evaluate the expressions.

-9,4(225) = -9.4 * 225 = -2115 1® = 1 (since any number raised to the power of 1 is the number itself) 6 . (10) = 6 * 10 = 60 1 + 9 = 10

Step 6: Substitute the evaluated values back into the expression.

-2115 : 1 — 60 . 10

Step 7: Continue simplifying the expression.

-2115 : 1 — 600

Step 8: Perform the division and subtraction.

-2115 — 600 = -2715

Therefore, when a = 1 and b = -1, the given expression evaluates to -2715.
