Question : 22

Total: 50

. Translate 2m

^2

+ 3n- 9 as a BASIC arithmetic expression.

Solution:

Concept:

BASIC uses

*

for multiplication and

\text{\^{}}

for power.

Explanation:

We need to rewrite

2m^2 + 3n - 9

using BASIC operators.

The term

2m^2

means

2 \times m^2

, so it becomes 2 * m ^ 2.

The term

3n

means

3 \times n

, which becomes 3 * n.

Keeping subtraction as it is, the full BASIC expression is:

2 * m ^ 2 + 3 * n - 9.

This matches the form given in Option B.

Answer:

Option B: 2 * m ^ 2 + 3 * n - 9
