Answer 1

Step-by-step explanation:

6) m=6,n=7

2(m square +mn) +3-mn

2(6square + 6×7) + 3 - 6×7

BODMAS rule is follow here.

Firstly solve brackets.

2(12+42)+3-6×7

Here square of 6 is 12 and 6×7 is 42 so i written this.

2(54)+3-6×7

Here i add. Now here ia bracket, so i will multiply 2 with 54

108 +3-6×7

Second multiply.

108+3-42

Here i multiply 6 and 7 =42

Third subtract

108 - 39 ( positive and negative is negative so i use - and subract 3 from 42)

108 - 39 = 69

This is your answer

7) when exponent is 0 then the value is 1.

(1-1)(1+1)

(0)(2)

Multiply 0 with 2

0

This is your answer

Hope it helps

Answer 2

Answer:

Q6. So lets substitute the variables to the constants given.

2(6*6+6*7)+3-6*7

2*78+3-6*7

156+3-42

159-42 = 117

So therefore the answer is 117.

Q7. Here this goes like this-

(6 degree - 2 degree) (6 degree+2 degree)

4 degree * 8 degree = 32 degree

So there fore the answer is 32 degree
