Q-4 VERY SHORT CALCULATION

3) Identify the terms and factors in 3y²+2

4) Using the law of exponent solve 6 ¹²×6²

5)What is the numerical coefficient of 3xyz

6) Convert 2.1 into percentage.​

please guys give answer

​

Answer 1

Answer:

See below

Step-by-step explanation:

1)

Area of sq = side ^2

= 5×5 = 25

2)

20/100 × 1km

= 1/5 × 1000

= 200m

3)

terms 3y^2 and 2

factors 3, y ,2

4)

6^12 × 6^2 ( by a^b × a^c = a^b+c )

6^12+2

6^14

5)

numerical coefficient = 3

6)

% = a/b ×100

= 2.1/1 × 100

= 210 %

Answer 2

Answer:

Step-by-step explanation:

3) Terms are:

3y²  and 2

Factors not possible

4)

$\bf6^{12} \times 6^2\\\\=6^{12+6}=6^{18}$

5) In 3xyz

The numerical coefficient=3

6) 2.1

Percentage=2.1 *100=210 %
