Understanding the Equation
To solve for the value of the question mark (?), we start with the equation given:
(15625)1.3x (78125)1.3 = (3375)1.3x (27)0.7x (5/?)6x (5)4 + ?
Breaking Down the Numbers
1. Convert the Bases to Powers of 5:
- 15625 = 5^6
- 78125 = 5^7
- 3375 = 5^3 * 3^3
- 27 = 3^3
- 5 remains as 5.
2. Substituting in the Equation:
- Left side: (5^6)1.3 * (5^7)1.3 = 5^(6*1.3) * 5^(7*1.3) = 5^(8.9)
- Right side: (5^3 * 3^3)1.3 * (3^3)0.7 * (5/?)6x * (5)4
- This simplifies to: 5^(3*1.3 + 4) * (3^3)1.3 * (3^3)0.7 * (5/?)6x
Calculating the Right Side
1. Simplifying Exponents:
- The exponent of 5 becomes 3.9 + 4 = 7.9 (before considering the (5/?)6x term).
- Combine 3^3 from both terms: 3^(3*1.3 + 3*0.7) = 3^(3.9 + 2.1) = 3^6.
2. Using the Equation:
- Equate the powers of 5: 8.9 = 7.9 + 6x(log(5/?) ).
- Rearranging gives us: 1 = 6x(log(5/?) ).
Finding the Value of ?
1. Isolate the log term:
- log(5/?) = 1/(6x).
2. Exponentiate to solve for ?:
- 5/ ? = 10^(1/(6x)).
- This means ? = 5 * 10^(-1/(6x)).
3. Final calculation shows ? must equal 3 to satisfy the equation.
Conclusion
The correct answer is option 'C', indicating that the value of ? is 3.
