Question

Verify the following

20 x [7 + (−3)] = [20x7] + [20x (-3)]​

Answer 1

It is verified that 20 x [7 + (−3)] = [20 x 7] + [20 x (-3)]​.

Given:

20 x [7 + (−3)] = [20 x 7] + [20 x (-3)]​

To Find:

Verify the following: 20 x [7 + (−3)] = [20 x 7] + [20 x (-3)]​

Solution:

We should use BODMAS to solve this question.

BODMAS stands for bracket, order, division, multiplication, addition, and subtraction.

20 x [7 + (−3)] = [20 x 7] + [20 x (-3)]​

LHS = 20 x [7 + (−3)] = 20 x [7 −3] = 20 x 4 = 80

RHS = [20 x 7] + [20 x (-3)]​ = 140 - 60 = 80

LHS = RHS = 80

Hence, it is verified that 20 x [7 + (−3)] = [20 x 7] + [20 x (-3)]​.
