Question

Q.1 Simplify: 15 - (-5) {4 - 7 - 3} / [3{5 + (-3) × (-6)}]? {2 MARKS}
it out​

Answer 1

15-(-3){4-(7-3)}=3[{5+(-3)*(-6)}]

By BODMAS Rule:

15-(-3){4-(7-3)}-3[[5+(-3)x-6}]

=15+3(4-4}-3[{5+18}]

=15+3{0}=3[23]

=15+3x0÷3x23

=15+3x0x23

=15+3x0

=15+0

=15

I use bodmas rule

mark me as brainlest

Answer 2

Step-by-step explanation:

$15 - (-5) {4 - 7 - 3} = [3{5 + (-3) × (-6)}]$

$15 - (-5) {4 - 7 - 3} = [3(23)]$

$15 - (-5) {4 - 7 - 3} =69$

$15 - (-5) {6} =69$

$15 - (-30) =69$

$45 =69 \\ 69 - 45 = 24$

hope it will help you
