Questions and Answers

Answer : A

Explanation

Step 1:

Using normal method

10-7 = $\frac{1}{10000000}$ = 0.0000001

Step 2:

The exponent here is minus 7. So using short cut, we put a decimal point then 6(1 less than 7) zeros and then a 1 to get answer.

10-7 = 0.0000001

Q 2 - Evaluate 10-2

A - 0.1

B - 100

C - 0.01

D - 0.001

Answer : C

Explanation

Step 1:

Using normal method

10-2 = $\frac{1}{100}$ = 0.01

Step 2:

The exponent here is minus 2. So using short cut, we put a decimal point then 1(1 less than 2) zero and then a 1 to get answer.

10-2 = 0.01

Answer : D

Explanation

Step 1:

Using Normal method

10-5 = $\frac{1}{100000}$ = 0.00001

Step 2:

The exponent here is minus 5. So using short cut, we put a decimal point then 4(1 less than 5) zeros and then a 1 to get answer.

10-5 = 0.00001

Answer : B

Explanation

Step 1:

Using normal method

10-3 = $\frac{1}{1000}$ = 0.001

Step 2:

The exponent here is minus 3. So using short cut, we put a decimal point then 2(1 less than 3) zeros and then a 1 to get answer.

10-3 = 0.001

Answer : C

Explanation

Step 1:

Using normal method

10-4 = $\frac{1}{10000}$ = 0.0001

Step 2:

The exponent here is minus 4. So using short cut, we put a decimal point then 3(1 less than 4) zeros and then a 1 to get answer.

10-4 = 0.0001

Answer : A

Explanation

Step 1:

Using normal method

10-10 = $\frac{1}{10000000000}$ = 0.0000000001

Step 2:

The exponent here is minus 10. So using short cut, we put a decimal point then 9(1 less than 10) zeros and then a 1 to get answer.

10-10 = 0.0000000001

Q 7 - Evaluate 10-1

A - 0

B - 0.1

C - 1

D - 10

Answer : B

Explanation

Step 1:

Using normal method

10-1 = $\frac{1}{10}$ = 0.1

Step 2:

The exponent here is minus 1. So using short cut, we put a decimal point then no(1 less than 1 is 0) zeros and then a 1 to get answer.

10-1 = 0.1

Answer : D

Explanation

Step 1:

Using normal method

10-6 = $\frac{1}{1000000}$ = 0.000001

Step 2:

The exponent here is minus 6. So using short cut, we put a decimal point then 5(1 less than 6) zeros and then a 1 to get answer.

10-6 = 0.000001

Answer : C

Explanation

Step 1:

Using normal method

10-8 = $\frac{1}{100000000}$ = 0.00000001

Step 2:

The exponent here is minus 8. So using short cut, we put a decimal point then 7(1 less than 8) zeros and then a 1 to get answer.

10-8 = 0.00000001

Answer : A

Explanation

Step 1:

10-9 = $\frac{1}{1000000000}$ = 0.000000001

Step 2:

The exponent here is minus 9. So using short cut, we put a decimal point then 8(1 less than 9) zeros and then a 1 to get answer.

10-9 = 0.000000001
