Master Answer- Carbs such pizzas and burgers are very harmful for us. So,they should be consumed in the least amount. Minerals are micronutrients so they should be consumed in less amounts. Fats give us energy so they must be consumed in high quantities. Proteins build our muscles and should be consumed in higher quantities. thus, option D.

Class : Class 10
(First Column) (3 X 5 X 4) – 36 = 24 = 2 to power 3 2 to power 4Note: Exponential power 3 = from first column first cell, Exponential power 4 = from first column third cell(Second Column) (Ans 4 X 4 X 4) – 32 = 32 = 2 to power 4 2 to power 4Note: Exponential power 4 = from second column first cell, Exponential power 4 = from second column third cell(Third Column) (5 X 7 X 6) – 114 = 96 = 2 to power 5 2 to power 4Note: Exponential power 5 = from third column first cell, Exponential power 4 = from third column third cell

Ans 4:

Class : Class 7
What is the solution for this?

Ans 5:

Class : Class 8

Ans 6:

Class : Class 10
(First Column) (3 X 5 X 4) – 36 = 24 = 2³ 2⁴Note: Exponential power 3 = from first column first cell, Exponential power 4 = from first column third cell(Second Column) (Ans 4 X 4 X 4) – 32 = 32 = 2⁴ 2⁴Note: Exponential power 4 = from second column first cell, Exponential power 4 = from second column third cell(Third Column) (5 X 7 X 6) – 114 = 96 = 2⁵ 2⁶Note: Exponential power 5 = from third column first cell, Exponential power 4 = from third column third cell

Ans 7:

Class : Class 9
where is the solution?

Ans 8:

Class : Class 10
(First Column) (3 X 5 X 4) minus 36 = 24 = 2 to power 3 2 to power 4Note: Exponential power 3 = from first column first cell, Exponential power 4 = from first column third cell(Second Column) (Ans 4 X 4 X 4) minus 32 = 32 = 2 to power 4 2 to power 4Note: Exponential power 4 = from second column first cell, Exponential power 4 = from second column third cell(Third Column) (5 X 7 X 6) minus 114 = 96 = 2 to power 5 2 to power 4Note: Exponential power 5 = from third column first cell, Exponential power 4 = from third column third cell
