Question

(-10)×{(-7)+(-9)}={(-10)×(-7)}+{(-10)×(-9)} step by step solve it fast​ give correct answer

Answer 1

Step-by-step explanation:

LHS = (-10)×{(-7)+(-9)}

RHS = {(-10)×(-7)}+{(-10)×(-9)}

Solving LHS,

(-10)×{(-7)+(-9)}

(-10)×{-16}

160 ( Multiplying 2 negative numbers give positive )

Solving RHS,

{(-10)×(-7)}+{(-10)×(-9)}

{70}+{90} ( Multiplying 2 negative numbers give positive )

160

LHS = RHS

Hence proved

Step-by-step explanation:

QUESTION

(-10)×{(-7)+(-9)}={(-10)×(-7)}+{(-10)×(-9)}

FORMULA USED

BODMAS

• BRACKETS
• OF
• DIVISION
• MULTIPLICATION
• ADDITION
• SUBTRACTION

THIS MEANS FIRST WE OPEN BRACKETS OR SOLVE THEM THEN, OF WHICH MEANS ✖ THEN DIVISION THEN MULTIPLICATION THEN ADDITION AND AT LAST WE PERFORM SUBTRACTION

SOLUTION

$(-10)×((-7)+(-9))=((-10)×(-7))+((-10)×(-9)) \\ - 10 \times - 16 =70 + 90 \\ 160 = 160 \\ lhs = rhs$

hence verified

this is correct equation due to distributive property
