Question

HELPPPPP MEEE PLEASEE

Answer 1

answer : 11

explanation: a2

$a ^{2} + 3b \div c - 2d \\ {3 }^{2} + 3(8) \div 2 - 2(5) \\ 9 + 24 \div 2 - 10 \\ 9 + 12 - 10 \\ 21 - 10 \\ = 11$

• 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☆☆☆
