Solve 3ab*3ab

$$3 a b \cdot 3 a b$$

Evaluate

$$9\left(ab\right)^{2}$$

Steps Using Commutative Property of Multiplication

Use the rules of exponents to simplify the expression.

$$3^{1}a^{1}b^{1}\times 3^{1}a^{1}b^{1}$$

Use the Commutative Property of Multiplication.

$$3^{1}\times 3^{1}a^{1}a^{1}b^{1}b^{1}$$

To multiply powers of the same base, add their exponents.

$$3^{1+1}a^{1+1}b^{1+1}$$

Add the exponents 1 and 1.

$$3^{2}a^{1+1}b^{1+1}$$

Raise 3 to the power 2.

$$9a^{1+1}b^{1+1}$$

Add the exponents 1 and 1.

$$9a^{2}b^{1+1}$$

Add the exponents 1 and 1.

$$9a^{2}b^{2}$$

Differentiate w.r.t. a

$$18ab^{2}$$
