To express 48 as a product of prime numbers using exponents, we first need to factor 48 into its prime components.

Starting with 48:

  • Divide by 2: 48 ÷ 2 = 24
  • Divide by 2 again: 24 ÷ 2 = 12
  • Divide by 2 again: 12 ÷ 2 = 6
  • Divide by 2 again: 6 ÷ 2 = 3

Now we have:

  • 48=24×31

So, 48 as a product of prime numbers using exponents is: 24×31

Among the provided responses, the correct representation is: 2 Superscript 4 Baseline times 3 (which represents 24×3).

To express the number 100 as a product of its prime factors, we start by factorizing 100:

  1. Divide by 2: 100÷2=50
  2. Divide by 2 again: 50÷2=25
  3. Now, we factor 25, which is 5×5 or 52.

So, the complete factorization of 100 into its prime factors is:

100=22×52

Among the provided responses, the correct representation is: 2 squared times 5 squared (which represents 22×52).

To express the number 80 as a product of its prime factors with exponents, we can factor 80 as follows:

  1. Divide by 2: 80÷2=40
  2. Divide by 2 again: 40÷2=20
  3. Divide by 2 again: 20÷2=10
  4. Divide by 2 again: 10÷2=5

Now we can express this as: 80=24×51

So, the correct expression of 80 as a product of prime numbers with exponents is:

2 Superscript 4 Baseline times 5 (which represents 24×5).

To express the number 120 as a product of its prime factors with exponents, we can factor 120 as follows:

  1. Divide by 2: 120÷2=60
  2. Divide by 2 again: 60÷2=30
  3. Divide by 2 again: 30÷2=15
  4. Now factor 15: 15=3×5

Putting this all together, we have: 120=23×31×51

So, the correct expression of 120 as a product of prime numbers with exponents is:

2 cubed times 3 squared times 5 (which represents 23×32×5). However, noting that the correct powers for the prime factors are 23×31×51, we have:

23 × 3 × 5 (which is the correct representation in the available options).

Thus, the correct answer from the responses is: 23 × 3 × 5 (2 cubed times 3 times 5).

To express 2×32×7 as a whole number, we can calculate it step by step:

  1. First, calculate 32: 32=9

  2. Now substitute that back into the expression: 2×9×7

  3. Calculate 2×9: 2×9=18

  4. Next, calculate 18×7: 18×7=126

Therefore, 2×32×7 as a whole number is 126.
