Question

1)2⁴-3=2) (-4) ³•0, 5+2•(-0, 2) ²=

Answer 1

1)16-3=13 это первый

Answer 2

Let's solve the expressions step by step:

1. 2⁴ - 3

2⁴ means 2 raised to the power of 4, which is equal to 2 * 2 * 2 * 2 = 16.

So, the expression becomes:

16 - 3 = 13

Therefore, the value of 2⁴ - 3 is 13.

2. (-4)³ • 0.5 + 2 • (-0.2)²

(-4)³ means -4 raised to the power of 3, which is equal to -4 * -4 * -4 = -64.

Now let's solve the expression step by step:

-64 • 0.5 + 2 • (-0.2)²

-64 • 0.5 = -32

(-0.2)² means -0.2 raised to the power of 2, which is equal to -0.2 * -0.2 = 0.04.

2 • 0.04 = 0.08

Now we can simplify the expression further:

-32 + 0.08 = -31.92

Therefore, the value of (-4)³ • 0.5 + 2 • (-0.2)² is approximately -31.92.
