Question

Evaluate the expression for b = 3 and c = 5.

b2c − 11 =

Answer 1

`b = 3 \ \: \: : c = 5 \\ \\ b {}^(2) c - 11 = \\ \\ \\ {3}^(2) * 5 - 11 = \\ \\ 9 * 5 - 11 = \\ \\ 45 - 11 = \\ \\ = 34`

Answer 2

• 34

Explanation:

• b = 3 and c = 5

Substitute and evaluate:

• b²c - 11 =
• 3²*5 - 11 =
• 9*5 - 11 =
• 45 - 11 =
• 34
