The equivalent expression of (1.4³/1.2⁴)⁻⁶ is gotten as; 1.2²/1.4³
<h3>How to use rule of exponents?</h3>
We are given the expression as;
(1.4³/1.2⁴)⁻⁶
Now, according to rule of exponents in multiplication, we know that;
x² × x³ = x² ⁺ ³ = x⁵
Thus, applying that rule of exponents above to our given problem and we have;
(1.4³/1.2⁴)⁻⁶ = (1.4³ ⁻ ⁶)/(1.2⁴ ⁻ ⁶)
⇒ 1.4⁻³/1.2⁻²
Also according to rule of exponents we know that;
x⁻¹ = 1/x
x⁻² = 1/x²
Thus;
1.4⁻³/1.2⁻² = (1/1.4³)/(1/1.2²)
⇒ 1.2²/1.4³
Thus, we can conclude about the question that the equivalent expression of (1.4³/1.2⁴)⁻⁶ is gotten as; 1.2²/1.4³

You could give an example or research into previous hypothesis and tests for the topic you are on.
You could also link your hypothesis to something opposite. (Eg: If you were looking at ice melting you may want to also look at how it freezes, this would show that even though something happens it reverses to its original state, in this case water.)
