Question

If `a=6` and `b=11`, what is `8(a^2-3b)-:8+3`?

Answer 1

Expession `=6`

Substitute the values given for a and b into the equation.

Explanation:

a = 6

b = 11

`= ((8(6^2 - 3(11)))/ color(red)(8+3))`

NB: Applying the hierachy of operators `-:` is applied before `+` unless parentheses are used to alter the hierarchy. The expression above should be written:

`= ((8(6^2 - 3(11)))/ 8)+3`

Corrections are shown in `color(red) (red)` below.

`= ((8(36-33))/ color(red) (8) )+ color(red)3`

`=color (red) (3+3)`

`=color (red) (6)`

The final solution should be `color (red) 6`
