Question

if a = -1,b = 15, c = -3, d =6 and e = -1, find the value of [ab+cde]​

Answer 1

Step-by-step explanation:

[ab+cde]=[(-1)(15)+(-3)(6)(-1)]

=3

Answer 2

Answer:

Given:-

If a = - 1, b = 15, c = - 3, d = 6 and e = - 1. Find the value of [ ab + cde ]

To Find:-

The value of [ ab + cde ]

Note:-

●》Here, we will put the values given and then multiply it as "ab" = a × b and then we will subtract or add the term according to their sign.

●》Negative × Negative = Positive.

Solution:-

$\huge\red{a = - 1, b = 15, c = - 3, d = 6 \ \ and \ \ e = - 1}$

$\huge\red{ \ \ \ \ The \ \ value \ \ of \ \ [ ab + cde ] = ?}$

☆ According to note first point~

▪︎$[ ab + cde ]$

☆ Applying the values~

▪︎$[ - 1 × 15 + - 3 × 6 × - 1 ]$

▪︎$[ - 15 + - 3 × - 6 ]$

☆ According to note second point~

▪︎$[ - 15 + 18 ]$

▪︎$[ 18 - 15 ]$

▪︎$3$

$\huge\green{[ ab + cde ] = 3}$

Answer:-

Hence, the value of [ ab + cde ] = 3.
