Simplify: $$\frac{(6a^4b^5)^2}{(3ab^2)^3}$$

$$\frac{36a^8b^{10}}{27a^3b^6} = \frac{4a^{8-3}b^{10-6}}{3} = \frac{4a^5b^4}{3}$$ .

Rewrite in simplified exponential notation: $$\frac{1}{3^{-2}}$$

$$3^{-2} = \frac{1}{3^2} = \frac{1}{9}$$ .

What is the product of two powers with the same base?

When multiplying two powers with the same base, you add the exponents. For example, $$x^a \times x^b = x^{a+b}$$ .

What is the power of a power rule?

The power of a power rule states that when raising a power to another power, you multiply the exponents. For example, $$(x^a)^b = x^{a \times b}$$ .

Simplify: $$(-2x^2y^4)^2 + (6x^3y^3)(2xy^5)$$

$$4x^4y^8 + 12x^4y^8 = 16x^4y^8$$ .

What is the definition of a square root?

A square root of a number x is a value that, when multiplied by itself, gives x. It is denoted as @@ oot{2}{x}@@.

What is the difference between rational and irrational numbers?

Rational numbers can be expressed as a fraction of two integers, while irrational numbers cannot be expressed as a simple fraction (e.g., @@ oot{2} $$, $$ rac{1}{3}@@).

What does it mean to simplify an expression?

To simplify an expression means to reduce it to its simplest form, making it easier to understand or solve.

What is the significance of exponents in mathematics?

Exponents indicate how many times a number (the base) is multiplied by itself. They are essential for expressing large numbers and for operations involving powers.

What is the relationship between radicals and exponents?

Radicals can be expressed as exponents. For example, the square root of x can be written as $$x^{\frac{1}{2}}$$ .
