The values from indices is;
a = 2
b = 3
What is exponential form?
The rules governing the manipulation and simplification of expressions involving powers (exponents) are called the laws of indices, or the laws of exponents. Fundamental to algebra, these laws aid in the simplification of expressions involving variables raised to powers.
The laws provide a systematic way to simplify expressions involving powers and are crucial for working with algebraic expressions and equations.
We have;
∛

Using the laws of indices

Hence;
a = 2
b = 3
