The equivalent expressions for 12−7 • 125 is (1/12)^2.
Equivalent expressions are expressions that work the same even though they look different. If the two algebraic expressions are equivalent, then the two expressions have the same value when we put in the same values for the variables.
The given expression is,
12^−7 • 12^5.
Since we know that,
x^a • x^b = x^(a + b)
Therefore,
12^−7 • 12^5. = 12^(-7 + 5)
or, 12^−7 • 12^5. = 12^-2
or, 12^−7 • 12^5. = (1/12)^2
The equivalent expressions for 12−7 • 125 is (1/12)^2.
Hence the required answer is one over twelve raised to the second power.
