Evaluating Expressions

From the question, we are to evaluate the given expressions

5. We are to find the quotient of

(21 ×10⁻²¹) ÷(7 ×10⁻²¹)

This becomes

(21 ÷ 7) × (10⁻²¹ ÷  10⁻²¹)

3 × 10⁻²¹⁻⁽⁻²¹⁾

3 × 10⁻²¹⁺²¹

3 × 10⁰

Thus, the quotient is 3 × 10⁰. The correct option is the second option

6.

We are to simplify (9.78 x 10−11)(3.4 x 10−18)

(9.78 x 10⁻¹¹)(3.4 x 10⁻¹⁸)

This becomes

(9.78 × 3.4) × (10⁻¹¹ × 10⁻¹⁸)

33.252 × 10⁻¹¹⁺⁽⁻¹⁸⁾

33.252 × 10⁻¹¹⁻¹⁸

33.252 × 10⁻²⁹

3.3252 × 10⁻²⁸

Thus, the simplified form of the expression is 3.3252 × 10⁻²⁸. The correct option is the last option 3.3252 × 10⁻²⁸

7.

We are to find the product of (2 × 10⁷) and ( 3 × 10⁷)

(2 × 10⁷) × ( 3 × 10⁷)

2 × 10⁷ × 3 × 10⁷

2 × 3 × 10⁷ × 10⁷

6 × 10⁷⁺⁷

6 × 10¹⁴

Hence, the product of the given expressions is 6 × 10¹⁴. The correct option is the last option 6 × 10¹⁴
