answer : 11
explanation: a2
[tex]a ^{2} + 3b \div c - 2d \\ {3 }^{2} + 3(8) \div 2 - 2(5) \\ 9 + 24 \div 2 - 10 \\ 9 + 12 - 10 \\ 21 - 10 \\ = 11[/tex]
- a2+3b÷c−2d
- 3^2+3(8)÷2−2(5) substitute the values in place of the letters
- 9+24÷2−10 use the relevant equation and find the value
- 9+12−10 according to the BODMAS u have to divide first (24÷2=12)
- 21−10=11
incase u didn't know what BODMAS is
B - brackets
O- order of powers
D-division
M-multiplication
A-addition
S-subraction
hope this helps☆☆☆
