Question

Use a = 7 and b = 28 to work out the value of these expressions.
ab =

Answer 1

Answer: 196

Explanation:

Our task is to evaluate the following expression:

`\sf{ab}`

We know that: a = 7 and b = 28; we plug these in:

`\sf{7*28}`

Then, we evaluate:

`\boxed{\sf{196}}`

Answer 2

ab = 7 * 28 = 196

Explanation:

o work out the value of the expression ab, where a = 7 and b = 28, we simply multiply the values of a and b together:

ab = 7 * 28 = 196

Therefore, the value of the expression ab, when a = 7 and b = 28, is 196.
