Exercise #1

53= 5^3=

Video Solution

Step-by-Step Solution

To solve this problem, we'll evaluate 53 5^3 , which means we need to calculate the product of multiplying the number 5 5 by itself three times.

  • Step 1: Compute 5×5 5 \times 5 .
  • Step 2: Compute the result of 5×5 5 \times 5 and multiply it by 5 5 again.

Let's work through each step:

Step 1: Calculate 5×5=25 5 \times 5 = 25 .

Step 2: Take the result 25 25 and multiply it by 5 5 :
25×5=125 25 \times 5 = 125 .

Therefore, the value of 53 5^3 is 125 125 .

Answer

125 125

Exercise #2

73= 7^3=

Video Solution

Step-by-Step Solution

To solve the problem of finding 73 7^3 , follow these steps:

  • Step 1: Understand that the power 73 7^3 means 7 multiplied by itself three times.
  • Step 2: First, compute 7×7 7 \times 7 . This equals 49.
  • Step 3: Next, multiply the result by 7 again: 49×7 49 \times 7 .
  • Step 4: Calculate 49×7 49 \times 7 , which equals 343.

Therefore, 73=343 7^3 = 343 .

With the possible choices given, the correct answer corresponds to choice 343 343 .

Answer

343 343

Exercise #3

43= 4^3=

Video Solution

Step-by-Step Solution

To solve this problem, we'll follow these steps:

  • Step 1: Apply the definition of powers to calculate 434^3.
  • Step 2: Multiply 4 by itself to find intermediate results.
  • Step 3: Verify the calculation against the given choices.

Now, let's work through each step:

Step 1: We need to calculate 434^3, which means multiplying 4 by itself a total of three times.

Step 2: First, calculate 4×4=164 \times 4 = 16. Then, multiply this result by 4 again: 16×4=6416 \times 4 = 64.

Step 3: The final result is 6464, which matches option 1 in the provided choices.

Therefore, the solution to the problem is 6464.

Answer

64 64
