Multiply 43 × 103
- 430
- 43
- 4300
- 43000
Hint:
Here we have exponent 3 of 10. Exponent is a power of any digit which multiply the same digit in exponent times. Here given is 43 x 103 and to solve that find the exponential value first and then multiply.
The correct answer is: 4300
Here , we are given the digit to multiply which are 43 x 10^3.
Firstly ,we are going to break this numbers into two form ,
Let a =43 which is a simple number and b=10^3 which is exponent part .
First, we are going to find the value b which is exponent part then find the value (axb)
Now,
b=103
b= 10 x 10 x 10 [ 3 is power of 10 , so we multiply 10 into 3 times]
b=1000
According to question ,we need to find out 43 x 103 which is a x b :
a x b = 43 x 1000 [ since , a=43 and b= 1000]
a x b = 43000
Therefore , the value of 43 x 103 is 43000.
The correct answer is 43000(option (b)).
The exponent is the power of a number which is exponent times of number . For example, 23 =2x2x2 . Here 3 is power of 2 which 3 times of 2. To proper and easy approach of this question is to solve the exponential part first then multiply the exponential part to the regular number.

Multiply 35 × 100.
Multiplication (often denoted by the cross symbol ×, by the mid-line dot operator ⋅, by juxtaposition, or, on computers, by an asterisk *) is one of the four elementary mathematical operations of arithmetic, with the other ones being addition, subtraction, and division. The result of a multiplication operation is called a product.
