= - 6  -10 x 1/2

= 6 x 1/2

= 60 / 2

= 30

Second Solution

To find the product of $(-6)\times \frac{1}{2}\times (-10)$

Explanation

4^3 = ?

= 4 x 4 x 4

= 64

Explanation

2^2-(2) +(-2) + (-2)^2 = ?

= 4 - 2 - 2 +(-4) 

= 4 - 2 - 2 - 4 

= - 2 - 2

= - 4

Explanation

Explanation

Explanation

Step 1: Recall the definition of a^0

Any non-zero number raised to the power of 0 is 1.

Step 2: Evaluate the options

𝑎/𝑎 = 1 (since any number divided by itself is 1, assuming 𝑎 ≠ 0)

𝑎^1−1 = 𝑎^0 = 1

Step 3: Determine the best answer

All the given options (𝑎/𝑎, 1, 𝑎^1−1) represent the value of 𝑎^0 correctly, assuming 𝑎 ≠ 0.

Explanation

j¹⁰⁵ = j^(4*26 + 1) 

= (j⁴)^26 * j¹ 

= 1²⁶ * j 

= j.

Explanation

= 4^3 + 2^5 - 2^7 

= 64 + 32 - 128

= -32

Explanation

7^2 means 7 squared, which is equal to 7 multiplied by itself:

7 x 7 = 49

So, 7^2 = 49.
