If a = 10, then which of the following represents 8,003 ?

A.) 8a + 3

B.) 80a + 3

C.) 8a² + 3

D.) 8a³ + 3

E.) none of these

A.) 8a + 3

B.) 80a + 3

C.) 8a² + 3

D.) 8a³ + 3

E.) none of these

10³ is 1000

8a³ + 3

= 8(10)³ + 3 {substituted 10, in for a, into 8a³ + 3}

= 8(1000) + 3 {evaluated exponent}

= 8003 {multiplied and added}

8a³ + 3

= 8(10)³ + 3 {substituted 10, in for a, into 8a³ + 3}

= 8(1000) + 3 {evaluated exponent}

= 8003 {multiplied and added}

**D.) 8a³ + 3***Ask Algebra House*
