Solve (60cm)(49cm)=

$$( 60 cm ) ( 49 cm ) =$$

Evaluate

$$2940\left(cm\right)^{2}$$

Steps Using Commutative Property of Multiplication

Use the rules of exponents to simplify the expression.

$$60^{1}c^{1}m^{1}\times 49^{1}c^{1}m^{1}$$

Use the Commutative Property of Multiplication.

$$60^{1}\times 49^{1}c^{1}c^{1}m^{1}m^{1}$$

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

$$60^{1}\times 49^{1}c^{1+1}m^{1+1}$$

Add the exponents 1 and 1.

$$60^{1}\times 49^{1}c^{2}m^{1+1}$$

Add the exponents 1 and 1.

$$60^{1}\times 49^{1}c^{2}m^{2}$$

Multiply 60 times 49.

$$2940c^{2}m^{2}$$

Differentiate w.r.t. c

$$5880cm^{2}$$
