Step-by-Step Solution

The goal is to compare the values of the expressions 74 7^4 , 83 8^3 , 102 10^2 , and 1112 11^{\frac{1}{2}} to identify the one with the highest value.

Let's calculate each expression:

  • Calculate 74 7^4 :
    - 74=7×7×7×7 7^4 = 7 \times 7 \times 7 \times 7
    - 7×7=49 7 \times 7 = 49
    - 49×7=343 49 \times 7 = 343
    - 343×7=2401 343 \times 7 = 2401
    Therefore, 74=2401 7^4 = 2401 .
  • Calculate 83 8^3 :
    - 83=8×8×8 8^3 = 8 \times 8 \times 8
    - 8×8=64 8 \times 8 = 64
    - 64×8=512 64 \times 8 = 512
    Therefore, 83=512 8^3 = 512 .
  • Calculate 102 10^2 :
    - 102=10×10=100 10^2 = 10 \times 10 = 100 .
    Therefore, 102=100 10^2 = 100 .
  • Calculate 1112 11^{\frac{1}{2}} (the square root of 11):
    - 1112113.3166 11^{\frac{1}{2}} \approx \sqrt{11} \approx 3.3166 .
    Therefore, 11123.3166 11^{\frac{1}{2}} \approx 3.3166 .

Now, let's compare these values:

  • 74=2401 7^4 = 2401
  • 83=512 8^3 = 512
  • 102=100 10^2 = 100
  • 11123.3166 11^{\frac{1}{2}} \approx 3.3166

Clearly, 2401 2401 is the highest value among these, which is obtained from 74 7^4 .

Therefore, the expression with the highest value is 74 7^4 .

Answer

74 7^4
