The expression determined when the negative exponents have been eliminated is A³b²/a
Index forms are described as models that are used in the representation of numbers or variables that are too large or small in more convenient forms.
To determine the expression the negative exponents have been eliminated, we have that the expression is given as;
Take the inverse exponent of the denominator and subtract, we have that;
A³b⁻²⁺⁴/a
add the exponents, we get that;
A³b²/a
