Step-by-step explanation:
Sarah's teacher wrote this expression on the whiteboard. 24 ÷ 6 − 2 × 5 + 6 Where could she place brackets in the expression for it to be equal to 36? A. 24 ÷ [6 − 2] × 5 + 6 B. 24 ÷ 6 − [2 × 5 + 6] C. [24 ÷ 6] − 2 × 5 + 6 D. 24 ÷ 6 − 2 × [5 + 6]
Rule of operations
BODMAS
B = Bracket
O = 0f
D = Division
M = Multiplication
A = Addition
S = Subtraction.
Check all options
A. 24 ÷ [6 − 2] × 5 + 6
= 24 ÷ (4) × 5 + 6
= 6 × 5 + 6
= 30 + 6
= 36
B. 24 ÷ 6 − [2 × 5 + 6]
= 4 - (10 + 6)
= 4 - 10 + 6
= 0
C. [24 ÷ 6] − 2 × 5 + 6
= 4 - 10 + 6
= 0
D. 24 ÷ 6 − 2 × [5 + 6]
= 4 - 2(11)
= 4 - 22
= -18
Option A is the correct answer

Step-by-step explanation:
g(x)= -16x² + 72x + 80
Plug 2 in to check if it's correct.
g(2)= -16(2)² + 72(2) + 80
-16(4)+128+80
-72+128+80
= 136
We have to write
In log form
To convert exponential equation to log equation, we have to use the following rule
So we will get
or
And that's the required log form .
